When I was coming out in the 70s it was common to spend a few months claiming to be bisexual as a uh gateway orientation on the way to accepting oneself as gay. I got over it.

Longitudinal studies of so called "trans" (sorry, I hate that word) teens often show that they end up being gay and return to comfort with their biological gender, and now that "trans" is supposed to be trendy an' cool it's a safer temporary accommodation.

Picture a girl who hides behind "trans" for a year or two, then the leading fad switches back to some clothing and hair style e.g. punk or goth, and now she's a lesbian and female except she has no breasts anymore.

Way to go.

We should absolutely not be encouraging this and we should be a lot LOT more skeptical about such claims.

Edit: male bisexuality is really rare. Most are like me, capable of enjoying heterosexual sex but making no claim to being bisexual; most men who do so claim lean very asymmetrically one way or the other and it is almost always gay.
