Does anyone else think they're a gay man in a woman's body?

I do, lately it hasn't left my mind...

Nope never. Actually, the thought itself is quite hard to even wrap my head around...

I had a friend who says she feels that way. She said it on more than one occasion. She was sort of a masculine girl...tended to be more of a tomboy, even in her thirties, so she felt out of place with a lot of other women who by that age behaved and presented much differently. She's got a boyfriend that she's been with for like 12 years or something.

I have gender dysphoria where I mostly feel like a boy in a girl's body but I'm really confused about my sexuality so I don't know if I'm gay yet

I can't even figure out what that means.

That's what happens when you think gender rolls exist.

I don't personally feel this way but known people who have. Usually their gender it is something they have always felt, even at a very young age

And I know it can sound confusing but it's not. Gender identification and sexuality are two totally different things.
Gender is how you identify in your head (regardless of what your genitals say).
Sexuality is who you find attractive and would like to go past first base with.

Easy peasy lemon squeezy

Eh I think I know what you mean, although in my case it's more that I "look" or "act" like a lesbian I guess. As Rigning said though, that's just gender roles, it's just a social construct that a straight woman has to look and act a certain way, or a lesbian has to act/look a certain way etc.
I try not to let it get to me too much anymore but it's still hard being myself sometimes, when I feel like "acting lesbian," but people will read something into it that wasn't intended at all.

If you meant that you wish you had a d*ck though, I also have felt that my whole life. Not as in gender reassignment tho, I just wanna know how it feels lmao.
