No I didn't, you came to that conclusion yourself.
Though, it is true that homosexuality is an oddity when you consider that humans need a man and a woman in order to produce children, and that's basically the whole purpose or drive behind sex. The pleasurable aspect is just a chemical based reward system that the brain has worked out in order to get people and other life forms to actually "do it".
I wouldn't worry too much about that though. That kind of stuff tends to go over the heads of simpletons, if they want to be offended by facts, I don't really care, lol.
