Basically, I don't believe that sexual perfrences really exist, like we will eff anything. I'm saying this because if we look at the ancient Greece they were mostly gay, and now it's the opposite, which means that sexuality is merely a social construct and we as a specie don't have any predisposition to one sex or the other. Prove me wrong
I think you mean to say "sexual orientation" (in the fixed, categorical sense) is a bit of an illusion. You may not be Mr. Diplomat, but you're not wrong, IMO!
