QotD: Mutability of Human Sexuality

Today's QotD is NSFW, so it's in the extended entry. If adult language will offend you, don't go there.

[. . .] there's no parallel imbroglio in the gay community is because adult gay men rarely, if ever, decide to change their gender. I've been out of the closet for more than two decades now (since I was 7 years old), and in all that time, I've never known a single adult gay man who decided — particularly in midlife — to run off and become a woman. The only men I've known who changed their gender as adults were heterosexually identified men who now identify as lesbians.

However, I've known lots of lesbians who later decided that they were and always had been men, and many more lesbians who decided they were and always had been heterosexual. At the risk of being burned in effigy at the next dyke march, the fluidity of female sexual identity sure does make me appreciate the solidity of male sexual identity. While I have to worry about my boyfriend leaving me for another man (he assures me that my worries are irrational — but he would, wouldn't he?), I don't have to worry about him walking into the kitchen one day and announcing that he's always been a woman, or that he's only just realized that he's straight. A guy that's sucking cock at 18 will be still be sucking cock at 28, 38, and 108 — but it seems that a woman can be eating pussy at 18, sucking cock at 28, and having her cock sucked at 38.
