Well, this certainly is an eye-opening thread. Surprised it took so long to open it.
As has been pointed out, the scale is too narrow to describe the rich variety of human sexuality. I’m reluctant to pick a number.
I think that 1 comes closest to fitting the bill, although depending on how you interpret “self-concept,” it could go as high as 3.
All of my 1-1 relationships have been heterosexual. Between the ages of 19 and 24, I was involved in three menage a trois, so I guess I’ve shared a fair amount of sack time with guys, when it comes to that. (These were real menage a trois: exclusive, durative relationships, and not casual “threesomes.”) Seemed natural enough at the time, although in retrospect I think that it gets complicated enough when people pair off.
More to the point, as a teen, more of my friends were gay than not, ostensibly because I hung with the “art” crowd. I had something of a crush on my friend Martin, author of the celebrated Blue Board for the C64. (Good ol’ BBS days.) He was het, as far as I know, although he was quite effeminate. I was equally attracted to his girlfriend, who fit the stereotype of a butch lesbian, crewcut, army-boots, and all. (She was the grandaughter of a famous Canadian anarchist, and had a massive intellect herself.)
I distinctly remember feeling terrible shame for being frightened and repelled at the idea of actually having sex with a male, which I suppose has given me a certain amount of empathy for the plight of gay teens trying to fit in with their heterosexual peers.
On reflection, it occurs to me that a large part of the aversion may have come from ignorantly equating gay sex with anal sex. (The thought of anal sex with anyone, regardless of gender, gives me the willies. More of a prude than I like to think, I guess.)
I find androgynous people more attractive, on the whole. People who are either “hyper-male” or “hyper-female” appear somewhat ridiculous and incomplete to me.
People often assume I’m gay because I apparently sometimes dress “gay.” (Uh, lavender is a favourite colour, I sometimes do the leather thing, lately I’m partial to all white cottons. For the life of me I’m not sure what the frequency of the light reflecting off of me has to do with my sexuality, but some people superstitiously interpret it that way.) I like a lot of things that people consider “girly.” Big Jane Austen reader, for instance.
I like it when women or men show an interest. The best day I had last year, I was having a coffee in Vancouver’s West End, and was chatted up twice in the time it took to finish my bagel- 1F, 1M-- then I walked 4 blocks to my GF’s and had an afternoon of glorious shagging. How validating is that?
Feh, I’m babbling.
Long story short, I cultivate (and appreciate) androgyny, but haven’t had homosexual sex as of this writing, although I’ve been as close to it as farting is to shitting. But “never say never.” I wouldn’t rule out the possibility that some guy might charm the pants off me the day-after-tomorrow.
Where the hell does that fit on the linear scale?
