I like women. I like the shape and curves of the female body. I like boobs, I like asses, I like pretty vaginas. I also appreciate and am aroused by a nice cock. I’m however not otherwise attracted to the male body. I like femboys as long as they have a feminine-like shape and curves, as many of them do.
WTF is my sexual orientation?
Bisexual is simply someone that is attracted more than one gender. Nothing to do with masculinity or femininity, so in this case, as I said, it’s a perfectly acceptable label. But if it doesn’t help the OP navigate the world or understand themselves, then it’s not the right label for them. If gynephilia does help them, then that’s the right term.
