I'm FTM, so I'm kind of the opposite of everyone else posting here, but yes when I came out as trans, I definitely found that my interests started changing. When I lived as a 'girl,' I spent most of my time writing poetry and reading literature, and since I've been out as a guy, I love hanging out and watching football and playing pickup basketball games with my friends. Yes, I did eventually get out of it to an extent, because now I still like to write poetry sometimes and I'm getting my old interests back. So for MTF, FTM, or anyone else, I really do think there's a personality shift when you come out no matter what, and there's nothing wrong with that; but in the long run, don't force old hobbies. Just do what makes you happy 🙂
