I am not debating homosexual orientation. I am debating homosexual behavior and every adult knows exactly what that is.
I don't think every adult knows exactly what that is. I think there are preconceptions, some of which are within domain of such behavior, but arguably a whole lot that isn't. Such that if two males are in a relationship and both are strictly against anal sex, I think it would confuse a few people as to what kind of sexual relationship they may enjoy together. Plus, there's the idea of foreplay or non-intercourse, non genital touching that would make for gray lines/confusion. If two males are hugging, is this homosexual behavior? Is it just two males embracing each other, in loving way, that makes for such behavior? I would think most people (probably mostly females) would say no. But surely some guys would see that as 'gay' and something to avoid, cause of feelings it could bring up in either of the males. Yet, imagine if such behavior was enough for two males who both self reference as homosexual. Or if it's more than this, but still not genital touching, as in full body (or nearly full body) massages being given to each other in loving way. Yet, neither is attracted to each other. I think some guys see that as gay. Me, I've had that done to me, massage from male in loving, caring way, but not a sexual way. Was clear to me this was not going to lead to sex/touching of genitals. At times, I definitely prefer such a thing from a male than female. Other times, I prefer a female touch.
If genitals are being touched, in sexual way, I'd draw line and call that sexual intercourse. For others, I've seen that not being considered intercourse, such that Bill Clinton didn't have sexual relations with Lewinsky, cause you know, people give other people head all the time, and have stains on the dresses to prove it.
Yet, if genitals are not being touched, I'd still consider it sexual. Yet, not strictly sexual, as it could be more loving, caring, nurturing than whatever the connotations are around sexual behavior. I know plenty of female attracted males who if a female just touches/embraces their forearm while they are having a conversation (both a fully dressed), they consider this a come on, and are sure the woman is into them. I mean, why else would she engage in such an action if she wasn't at least a little attracted to the guy, enough to touch/embrace him, in a friendly/loving way? Are guys slapping each other on the butt (fully clothed) engaged in homosexual behavior? Could both be straight, but the question remains, is that homosexual behavior?
These questions, and more can (easily) be asked, and is why I am fairly certain not every adult knows exactly what makes for homosexual behavior. And given all the unwritten stuff that makes for sexuality (all of it), I actually feel like there's a small handful of people that get it, and a whole lot of people that more or less need to be hit over the head for it to be discernible to them.
