Let's Fuck!
Anybody interested in getting laid? With me of course! All comers welcome. Male or female.
Now before you get all upset, let me explain. If we were like Bonobo chimps, the above statement would generate no controversy. Your response might be, "Uh, I could fit you in at 4:30, but you'd have to hurry because Mike is coming by at 6, and Lisa is scheduled for a 3:00 o'clock session." Bonobos are of course famous for living an orgiastic existence, involving both gay and straight sexual activity. But I suspect if I truly said the above in polite society (and even not so polite society), I'd be run out of town and tarred and feathered. But at the same time, we all crave sex and fantasize about living the Bonobo chimp lifestyle - heterosexually if not bisexually at least. Sex is pleasurable; so why don't we constantly do it? And what difference would it make if you're in a relationship? Why would your partner care if you engage in pleasurable activities without him/her? I suspect you do a lot of things that you enjoy without your partner. Why should sex be any different?
And why should it matter if it were gay or straight sex? Presumably gay sex is pleasurable as well. But why then are heterosexual people turned off by it?
So what's the big deal? Let's get naked!

Bonobos are the perverted uncle of the ape family tree.
Granted, chimps[ent]mdash[/ent]like humans[ent]mdash[/ent]wage war for resources much like humans and unlike bonobos, and bonobos can be admired for that, but I find the "use sex for every kind of social interaction" kind of creepy. Bonobos are very closely related to chimps and humans, so there is every reason to believe that they might have heterosexual and homosexual individuals.
If I am correct about that, this means that their culture is such that they simply expect homosexuals to have sex with the opposite sex and heterosexuals to have sex with the same sex.
Uhm.
Ew.
I suppose it's possible that they are all bisexual by birth, but until someone can figure that out biologically, I'm going to assume they're expecting individuals to have sex with a gender they aren't attracted to. Yuck.
I beg to differ.
That "Ew" itself is in large part cultural. There was one longtitudinal study in Germany (if you're interested, I can try to dig up the citation) that found that young men were experimenting with same-sex stuff at much higher rates in the 50s, 60s, and 70s than today, and iirc they explained in that today's men are more afraid to be (seen as) gay than men were when gays weren't so visible. The notion that you have to be gay to enjoy an occasional blowjob by another man is probably not instinctive - lips are lips, assuming he's decently shaved, and if he isn't, you might learn a valuable lesson about what it feels like for your girlfriend when you aren't.
To me that confirms that there is a cultural component involved, but it does not convince me that there is no genetic component. My interpretation of that study would be that sexuality is much more fluid than historical, conservative societies classically allowed for. So yes, culture can act as a deterrent to homosexual behaviour, but I do have my doubts that our tendency of disinclination towards it is entirely social. Genetically, heterosexual behaviour is adaptive, and homosexual behaviour is maladaptive, so in theory we should see people who are more interested in homosexuality fall out of the population.
Coming from personal experience, I have absolutely no desire to have a sexual encounter with any man, and I'm about as comfortable with homosexuality as it gets. I just do not find men physically attractive. Often intellectually attractive, yes, but never physically.
