> [@Mijin](#): > > I think the revulsion is biological, but giving a massive crap about what people do in privacy, is cultural. Exactly. The fact that homosexuals exist and have sex with each other doesn’t bother me in the least, and I fully support gay rights. As a straight male, the only revulsion I have is with the idea of myself being intimate in any way with a man. I believe that this revulsion is biological in origin. > [@Mijin](#): > > My reasoning is that it isn’t just gay sex that we find repulsive. Any sex which does not involve at least one person that we find attractive, or involves acts that we wouldn’t find appealing to do, is generally unpleasant to watch or think about, not merely neutral… I came in here to say this, but from a slightly different angle. I find watching sex (or even just kissing) pleasurable if I can imagine myself in the place of one of the participants, and unpleasant if I would NOT want to be one of the participants. This is why I avert my eyes if I see two men kissing (Torchwood, I’m looking at you!), and why I would never watch gay male or bondage or scat porn, and why lesbian scenes don’t bother me (though I don’t seek them out), and why I don’t watch porn that has ugly women in it. My discomfort has nothing to do with the idea of gay sex, but more with the (involuntary) thought of myself being a part of it. ---

> [@Acid\_Lamp](#): > > Probably a very small bit of biological, and and whopping helping of cultural. In my own case, I fall squarely into the category of: “I don’t care, but I don’t want to see it either.” Why? I suppose it’s because as a hetero male I do not find men arousing. As they are engaging in an act I know to be erotic, my disinterest conflicts with my knowledge of what I am viewing. That conflict is resolved in my mined by placing it into the the rather childish category of “ick”. I think this pretty much covers it. The fact that we have pretty well documented cultures in which even ostensibly straight men engage in gay sex (ancient Greece and Rome, modern Afghanistan, etc.) makes it _highly_ unlikely that there’s a significant biological element. ---

To give a particularly glaring example, in most oral footage, the camera frame is dominated by an erect penis and female bits get little if any air time at all, and, again, this is in porn specifically designed for and marketed at straight men. If there really was widespread revulsion at ogling another guy’s junk, it would stand to reason that much more effort would be made to avoid those sorts of scenes & angles, not play them up. Why is it called a “money shot” if it’s supposedly so gross? > > Then there’s the rather less openly obvious issue of how much gay sex goes on without being mentioned. As a personal anecdote, I’ve had sexual encounters (occasionally regularly) with almost every other male I’ve gotten to know well over the course of my life, and 3/4ths of them identify as 100% straight before, during and after and would not dream of ever mentioning it in public. As with all anecdotes, it’s entirely possible I’m an outlier, but I suspect there’s a lot more of that going on that is acknowledged. “Sure, I’ve masturbated with my buddy every other Saturday night for the last two months, but that’s not _gay_.” > > To sum up, I think the common refrain of “I don’t want to know anything about it! Ew!” is simply that the average American socialized male doth protest too much. I think that you are missing the point re: the porn. In an oral scene, the camera only has so much field of view it can focus on. Lots of men like to watch as their partner performs the act on them. The director has a choice; focus on her face and what she’s doing, or focus on her other attributes which can be difficult because of necessary positioning, and take away time from the more common fantasy. I also don’t think that men find penises revolting in general. They like their own, and imagine themselves in the scene. The money shot works the same way. As to the second part of your post, I’ve never had the sort of experiences that you think are common. I think that you are indeed an outlier, and not the norm. ---

I’d say that it’s cultural. Certainly not biological. A couple of examples in my own mind would be that homosexuality isn’t always looked on with revulsion or even social stigma. The Greeks spring to mind, though they aren’t exactly unique. Another example is (this is from memory) that chimps and monkeys will exhibit homosexual behavior when they are in a closed group (say, in captivity or otherwise isolated for long periods of time) in the absence of a female. This seems to indicate, to me at least, that biologically there is no revulsion factor, since it seems humans exhibit similar behavior (based on reading about rampant homosexuality in the Brit Navy during long deployments). As for the trope aspect given in the OP, I think that most people are hinked out about homosexual sex in our (presumably US) culture because, well, they are hinked out about ANY sex outside of their own bedroom. I know a lot of folks who go pale thinking about old people having sex, or about dwarves (or elves…hell, I know some folks who were hinked out about the sex in Avatar) having sex, or about…well, any sex that they aren’t having themselves. For my part, I’m not really interested in ANY sex (hetero, homo, interspecies or self inflicted) that I’m not a participant in. 😛 -XT ---

> [@spark240](#): > > Always with the procreation! Look, **almost all sex is non-procreative**. Right, but here’s the kicker: our gut reaction doesn’t know or care whether conception will actually occur. But if the idea of something that _could possibly_ lead to procreation arouses (and you could make a case that even heterosexual oral and anal sex fall under this as they could be considered foreplay to vaginal sex, even if the vaginal sex never happens) and something that _most certainly won’t_ lead to procreation (gay sex) doesn’t, does that not at least merit consideration of a biological component? **qpw3141** said it better than I so I’ll just quote him now: > [@qpw3141](#): > > The actual mechanism of revulsion is almost certainly an evolutionary trait. > > Any trait that would tend to stop someone from going down a reproductive dead end (same sex, post childbearing/child rearing age) or undesirable (closely related, obvious inheritable disability) would be advantageous to the passing on of the genes of that person. > > Since once you are sexually excited about someone/thing it can access the very powerful sex drive it would clearly be beneficial if there was anything in a persons makeup that would inhibit them from pursuing one of the above mentioned dead ends. > > Someone with a revulsion powerful enough to stop them succumbing to the sexual attraction of another with whom reproduction is impossible/undesirable would certainly be in a better position to pass on their genes. This makes a great deal of sense and was the line of thinking that I was using in the OP, but I still haven’t seen any actual cites on whether there have been any attempts to study this scientifically. ---

A lot of people have mentioned the Greeks, but just because gay sex was largely tolerated, how do we know that a significant if not majority of people were repulsed by it even in their culture? Maybe they just weren’t vocal about it because the powers that be supported it (and if Greek _women_ were repulsed by it, they certainly didn’t have a say). And from my limited understanding of ancient Greek culture (please correct me if I’m wrong), gay sex wasn’t unilaterally supported anyway - only in certain situations and under certain premises (older men with younger men, and the older man would be the “top”. If two younger men had sex or an older man was the receptive partner it would still be considered shameful). Taking exhibition of gay sexual behavior as an indicator of a lack of biological component is also shaky ground. Especially since you’re talking about situations where men (and the chimps) who would otherwise consider themselves straight resorted to homosexual behavior only after a period of isolation from women. In fact, that almost certainly seems to indicate an initial avoidance reaction (which doesn’t mean disgust/revulsion of course, but it could) that was eventually inhibited because of a sex drive powerful enough to overcome it. I’m just trying to play devil’s advocate here since most of the responses seem to be leaning toward the cultural side. I don’t doubt that a desire to fit in and exhibit machismo (and whatever the female equivalent is, since I’ve heard just as many or probably more women expressing a revulsion to gay sex as men) has contributed toward it, but I have trouble believing that’s the whole story. ---

[QUOTE=Rigamarole] A lot of people have mentioned the Greeks, but just because gay sex was largely tolerated, how do we know that a significant if not majority of people were repulsed by it even in their culture? [/QUOTE] The point is that, at least afaik, there was no social stigma attached to homosexual behavior (in these cultures)…which means there was not automatic revulsion factor. > [@](#): > > Maybe they just weren’t vocal about it because the powers that be supported it (and if Greek women were repulsed by it, they certainly didn’t have a say). No, I don’t believe that was the case. It was pretty wide spread throughout the various social and economic classes, and it wasn’t stigmatized. And, afaik, Greeks (and Romans for that matter) were human, not mutants. To me this seems to indicate that any revulsion factors present are culturally based, not biologically based. > [@](#): > > And from my limited understanding of ancient Greek culture (please correct me if I’m wrong), gay sex wasn’t unilaterally supported anyway - only in certain situations and under certain premises (older men with younger men, and the older man would be the “top”. That’s not my understanding, though I haven’t made an extensive study of it. My understanding is that on campaign, Greek men of equal social and economic status would often form sexual bonds, and that in some cases with elite troops it was required. And that such sexual bonds weren’t looked down on in any way, and in fact were seen as natural. I think in Rome some of what you are saying is true (i.e. the penetration vs penetrated…a dominance game basically), but again I don’t believe such relations were stigmatized to any great extent, which is the point. If there was a revulsion factor then you’d have an ingrained and automatic stigmatization of such behavior, since presumably it would be present in the majority of any given culture. Instead we have a rather spotty stigmatization of homosexuality that, to me at least, seems to revolve more around religious belief than any inherent biological revulsion to homosexuality. And then there is the fact that monkeys and chimps don’t seem to have any kind of revulsion reflex about such behavior, and (from memory…haven’t looked it up) participate in it in the absence of female partners. -XT ---

There’s a big difference between “don’t care to see it” and “revolting.” I don’t _care to see_ straight porn, but it doesn’t _revolt_ me (or rather, if a particular film revolts me, it’s on a basis other than the fact that there’s a woman involved). Listen, if it were biological in nature, wouldn’t the revulsion have to be universal and cross-cultural? ---

Incidentally, apes and monkeys of lots of species have been document engaging in extensive homosexual behaviour under numerous circumstances in the wild, not just when they’re in single-sex captivity. So have nearly 600 other species – in some cases homosexual sex has been observed in species where _heterosexual_ sex has never been successfully observed.

[/QUOTE] He was talking about the revulsion reaction you were theorizing. If such a reaction were biological we’d see it in some percentage of any given human population. Instead we see it clustered mainly in cultures who persecute or otherwise revile homosexuality for whatever reason (generally religious based). Even in cultures where it is looked down on there are many instances where circumstance makes otherwise heterosexual males have homosexual relations (like my example of the British Navy in the past)…which wouldn’t happen if there was in ingrained, reflexive and biological ‘revulsion reaction’. I can’t see how such a reaction could or would plausibly be biological in nature, since it seems highly dependent on the culture under discussion. Unless you are further positing that cultures also cluster high concentrations of humans with or without this biological ‘revulsion reaction’, and that this is also something unique to humans but only in certain clusters. That seems an awful lot of factors to pile up, when the simply Occam like answer is that it’s simply cultural factors that impact the view of homosexuality in a given grouping of humans. -XT ---

Homosexual _activity_ is not a dead end, though–it’s perfectly possible for an individual to reproduce before or after gay sex–just not _by_ that means. In fact, this must happen relatively often, given the reported incidence of sometime homosexual experiences among hetero-oriented men. Also, evolution isn’t just about individuals’ genes; it can be beneficial to a _population’s_ survival (say, in a band or tribe or village) to have non-reproducing individuals. > [@PaperBlob](#): > > As a straight male, the only revulsion I have is with the idea of myself being intimate in any way with a man. I believe that this revulsion is biological in origin. > … > I find watching sex (or even just kissing) pleasurable if I can imagine myself in the place of one of the participants, and unpleasant if I would NOT want to be one of the participants. This is why I avert my eyes if I see two men kissing… This kind of talk makes me a little sad. I’m not gay, never had gay sex or any interest in it, but I’m not _revolted_ by the idea. It just doesn’t turn me on, the same as some women don’t or wouldn’t turn me on. I _have_ had the experience of being an object of desire by at least one man and a couple women (that I knew of) which I could not reciprocate… and it just made me feel a little bad. Not sickened, just sorry, because my assumption has always been that the desire for intimacy, at its most basic level, is more or less the same for everybody, regardless of gender and orientation. And I know how it feels to be on the other side of that ache. On the other hand, I like seeing people who have found intimacy with someone and are happy with each other. I don’t need to watch them in bed, but I like seeing same-sex couples holding hands and kissing, just like opposite-sex couples. It has nothing to do with _me_–I’m happy for _them_. Discussions in this vein always seem to bring up the porn, and the idea of inserting oneself (heh) into a scene. Okay, your porn preferences are your own, no need to justify those–but when we’re dealing with real people, in person, can’t we put that mentality aside? A gay couple holding hands and kissing in public isn’t some kind of unwanted deviant pornography forced upon you–it’s not about you at all. They’re real people trying to live their lives and be close with someone, and that’s not revolting. It’s nice. ---

The reason that revulsion of activities that cannot lead to reproduction could be a useful evolutionary trait is that it would tend to prevent potential reproducers concentrating on some form of non-reproductive sex to the extent that in excludes reproductive sex. > [@](#): > > Also, evolution isn’t just about individuals’ genes; it can be beneficial to a _population’s_ survival (say, in a band or tribe or village) to have non-reproducing individuals. It’s not impossible and if you can come up with a credible theory as to how that would work and how it would outweigh a trait that would tend to concentrate activity on activities that could lead to reproduction, by all means let’s hear it. ---

> [@xtisme](#): > > [QUOTE=Rigamarole] > A lot of people have mentioned the Greeks, but just because gay sex was largely tolerated, how do we know that a significant if not majority of people were repulsed by it even in their culture? The point is that, at least afaik, there was no social stigma attached to homosexual behavior (in these cultures)…which means there was not automatic revulsion factor. [/QUOTE] That does not follow at all. Just because there is a cultural acceptance of something does not mean that the majority do not find it repulsive. It just means that they have the emotional maturity to mind their own business and not try and force their own views on others.
