Don't even bother. This person doesn't seem to be engaging in good faith to me. LolLogic does not dictate sexual orientation. I am not sure where you are going with that. Sexual orientation often defies logic.
I define my sexual orientation by which gender I am attracted to.
Look at it this way, if I close my eyes and get a blow job by a girl or a guy, could you tell the difference? The fact that I would enjoy a woman giving me a BJ does not make me straight.
With my specific case, it may be more complicated but the point I want to make still holds. Imagine back in the day when gay men got married and had kids because they couldn't come out. Those guys have often said sex with woman was OK. They enjoyed it just enough.
What makes me identify as gay is that I don't see myself dating or marrying a woman. I have no interest in living with a woman or having an emotional relationship with one. I am exclusively attracted to men. Sex with a woman would just be sex. Yes, I enjoy occasionally (like once in a blue moon) watching a woman finger herself or something like that lol but I would never prefer that over a guy.
It may be difficult to understand for you because maybe you don't have any kinks like that. We are all a little different.
I think you can be in the middle of the Kinsey scale but still self identify as gay. Key here is self identity. You need to realize and respect ppls identity.
Obviously anyone can choose to identify however they wish to. That isn't anyone else's decision to make nor is it "logic's" decision? Such a strange point. Lol
Yes sexual orientation for many goes beyond purely the physical biological facts. For some they do choose to identify based on that but for others they will not. And that's their right to. Often lifestyle, romance play significantly in the decision as opposed to just attractions.
There is a wide spectrum of bisexuality but not everyone wants to identify that way (esp if their dual attractions are vastly disparate)
