The Gay Male Gene has been Identified!

If, as my most devout and delusional homophobes assert, ONLY gay men experience pleasure when stimulated anally, wouldn't that mean that there is a gay gene or specific homosexual nerve endings or some biological and/or anatomical source of said anal pleasure that can be identified scientifically and we can dispel this stupid idea that homosexuality is not natural? I mean, if there is something that makes some men experience pleasure and others not experience it, that would clearly indicate to me that homosexuality in men is not a choice but rather a biological occurrence that makes homosexuality perfectly natural. It's like left-handedness: most people are right-handed but left handed people are not unnatural or freaks, just different.

Wait, you mean that no doctor or scientist has found this gay anal pleasure DNA sequence that allows ONLY homosexual men to experience pleasure when anally stimulated? Are you serious? Oh, okay, let's rethink this. There isn't anything that makes ONLY gay men experience pleasure anally so . . . what if . . . OK, stay with me . . . ALL men experience pleasure when they are stimulated anally and that has nothing whatsoever to do with their sexual orientation? That couldn't be possible, could it? Either there something that makes ONLY gay men experience pleasure when stimulated anally and that makes homosexuality as natural as say, red hair or blue eyes. If there ISN'T something specific that makes only gay men experience pleasure when stimulated anally, that means that all men have the potential and ability to experience pleasure when stimulated anally and receiving pleasure anally has nothing whatsoever to do with sexual orientation. So which one is it?
