I don't get it, this isn't a trans manga. I think about wanting to be a woman and in a lesbian relationship all the time, but that doesn't make me trans.
Ask any of your guy friends how often they think about wanting to be women and/or want to be in a lesbian relationship.
But all of my closest friends are sapphic women.
Ask your father if he's ever wanted to be a woman. Ask a colleague or classmate. Ask anyone.
And then, If any of your sapphic friends are trans women, ask them how they knew.
I did, a few years ago, and the answers I got have helped me a lot and made me a much happier person.
What if I said I have only been raised by women, have women relatives, and sapphic cis women friends? Should I ask any men in the thread right now?
