When I am sliding into one… its very sexy… 
I think there should be a sign or something above the hole: EXIT ONLY- DO NOT ENTER
Butts are sexy. If you study the evolution of human sexuality, you will find that, at the beginning of the origin of homo sapiens, humans still walked on four limbs for a time. Back then, men approached women from behind and copulated with them in the same way that most mammals do today. So the sight of a female butt was a very exciting thing to men. A woman shaking her butt was considered a signal of willingness or being in heat. This is still true today, though probably less so.
Some sexologists claim that the reason cleavage (especially of large chests) is so exciting to men today is because it reminds men of the sight of an upturned female butt, which brings to their subconscious mind thoughts of copulation.
Buttholes, on the other hand, serve no reproductive purpose, therefore are not sexy from an evolutionary point of view.
Well if you more or less rationaly look to much at sex and even the preliminaries you would stop having sex. Female Genitalia arent exactly “cute” looking. Mens equipment is stuffed all day long in his pants and he pisses with it.
Kissing !? No way… sharing all the germs of a whole days worth. Tongue and all. Getting a blowjob ? No way ! Sex with all those icky fluids going back and forth too.
Yet somehow our species continues… seems when we really like the person or we are completely horny we simply dont care. I myself licked away the “Exit Only” and my GF went nuts… great for me 
That she loves when I go in thru the backdoor… so much the better for me. If you wanna be prude and live your life with condoms and boring sex… you certainly will die without knowing good sex.
Give me a nice bum hole to play with anyday...I’d pretty much ignore that sign, in favor of “THIS SIDE UP.”
I thought those were called “stage doors.”
Yike! Where’d all these “missionary position only” people come from? Are bumholes sexy? Yes, of course they are! Situated between the cheeks of a lovely, round bum, and they’re so conveniently close to the Vertical Smile. The whole area is erogenous, except in some uptight people. Folks who have anti-erogenous zones should paint them in yellow-and-black warning stripes to ward off any alarming touches.
My wife aksed me this question just last week after we received some spam with pictures of women emphasizing their holes.
My answer: it’s not that the holes are sexy, it’s that the pose that emphasizes them that gives the viewer the message “Come on in” (no pun intended) that’s sexy.
I’m not exactly sure where alot of people are getting off stating that since certain body parts are not used for reproduction, it cannot possibly be sexy to anyone. My feeling is that this is an over-generalization of epic proportions.
Allow me to introduce you to the concept of “The Fetish”:
To those folks in this thread who think like our friend The Griffin:
No. The debate is far from over.
Hey, I know what you mean, especially in reference to ‘boring sex’.
There something oddly ironic, however, with your phrasing as far as ‘live your life with condoms’. Last I heard, there were fringe benefits for someone who chose this avenue of ‘prudery’. Surely you didn’t mean to project an attitude that discourages condoms, especially with such a sexual act?
I can’t think of any body part that isn’t sexy, on the right person.
I would definitely say they can be sexy, and they can certainly be cute. They are fun to lick and fun to fuck, so how could I not consider them sexy?
Armpit?
Knee?
Bottom of wrist?
Stomach?
Sure they’re sexy. Every part of the human body is/can be sexy. It also depends on the moment.
An asshole in the bathroom covered in crap = no sexy.
An asshole in the bedroom covered in oils = yes sexy.
Also, point of refference. By “asshole” I mean your bunghole, not Rush Limbaugh.
Yes.
Yup.
Couldn’t quite find this one, but how about a hand fetish?
Yup. It’s called alvinolagnia.
Have I convinced you that just about any part of the human anatomy can be found to be sexy? No? OK, try browsing a few fetish sites online. Go ahead! Do a search on google!
Yep, the elastic cuff on the sleeve of a raincoat! Oh babY!
I think the wrist is very attactive, especially the inner wrist, right were it meets the hand, if that counts. It’s not a full-blown fetish or anything, but it’s one of my favorite places to have kissed/to kiss, and I think they’re extremely attractive. I also think hands in general can be very sexy.

I don’t see how lacking an attraction to an asshole translates to “you only have sex in the missionary position/sexually uptight.” I’m a far cry from a “just missionary” girl. I’m very comfortable with my sexuality, love various sex positions and various sex acts…it’s just that assholes (assholes, not the ass, asses can be very sexy) and sex acts that involve the asshole hold very little appeal for me, epescially considering all the alternatives.
Regarding the fact that it’s an errogenous zone, I can only say, maybe for some people, but not for me. And not because I’m uptight…it just honestly does nothing for me.
I think I may have gotten a little carried away by the point I was trying to make in my previous post. I would ask that noone click on the first link, as this may create a bevy of unwanted pop-up ads. I’m also not sure whether the second link might be inappropriate for the SDMB. I apologize in advance, and ask the mods to remove the first link from my post, and to decide whether the second link should stay or not.
The third and fourth links (the hand fetish and alvinolagnia links) should be okay, I think.
Another vote for “yes”. The anus is chock full of nerve endings and is quite an effective erogenous zone, whether or not you engage in anal sex.
Round peg, round hole. It’s perfectly logical.
