In, I think, a similar vein, Belle Waring asks the following:
How much would straight men's homophobia have to die down to get to the point where hot guys would make out at parties and bars in an effort to attract chicks? Not before I am a dirty old woman, right? I mean, I have known guys to do this, but more because they were wasted and feeling experimental. I brought this up to John and he questioned whether women would think it was hot. My response was a deadpan, "I figure there's got to be room in there for me somewhere." More seriously, yes, women think gay guys getting together is hot.
Now, I always assumed women did not find gay guys getting together to be hot, evinced by the famous confusion women express over why guys find lesbian hook-ups hot. But I admit that I could be wrong, and the commenter who notes the appeal of yaoi fan-fic certainly has a point.
So then to answer Belle's question, I think we seem to be moving in that direction, at least if debate parties are any indicator. Faux-gay hookups, when I've observed them, seem to be less about signaling the surrounding women "look how hot I am", and more about "look how spontaneous, tolerant, and fun-loving I am" -- it's kind of part of the half-step being taking amongst today's youth wherein being gay isn't necessarily cool, but being tolerant of gay people is. You make out with another guy, you show you're not a homophobe. People who like non-homophobes are pleased.
Would be even better if we moved beyond that to straight guys hooking-up with gay men as a sexually arousing performance to pick up girls? Eh. The equality aspect appeals to me, but it feels a little low-brow. Then again, I guess I don't object when I'm the beneficiary. So, if it gets you off, I guess I have no objection.
