Why do some guys want to be girls?

Answer 1

'Why do some people have green eyes?' 'Why do some people have darker or lighter skin?' 'Why are some people tall and some short?'

"Guy" and "girl," "man" and "woman" refer to social and gender identities. They aren't contingent on one's physical disposition. I.e. just because someone has a penis (and thus was designated male at birth, DMAB) doesn't mean that that person feels like a boy. Sie might feel that this is a false or incomplete description of hirself. A DMAB person might want to be perceived as a girl in society. Often transgender people describe themselves as "a girl trapped in a male body" or "a boy trapped in a female body." For more information, look up "transgender."

A better way to ask your question might be:

"Why do some people want to experience life from the perspective of another gender?"

The answers are always different. They range from curiosity and creativity through wonder and excitement. Or it may have more to do with what that person identifies within themselves as.

Some people (who are male and identify as men) crossdress (dress up/put makeup on in a way that is commonly seen as feminine) because it's a sexual fetish for them or because they like feeling more feminine sometimes. It is important to distinguish crossdressing for fun from being transgender, which has nothing to do with sexual orientation or practices.
