When I first started transitioning, I worried about meeting social expectations, so I was concerned about everything. Like, "Oh my god, I can't play guitar anymore because I'll be seen as masculine", lol. Nowadays, it matters little to me. Men and women are diverse and you can be either masculine or feminine no matter your gender. I feel there is so much more to our gender than what hobbies we like.
This is something that I think men have a harder time with because feminine things are often looked down upon for a boy to do whereas women are often accepted for being tom boys. It sounds like you are feeling a little social pressure and trying to fit in with the guys. That's normal, but remember that all men are different. I know plenty of guys that enjoy fashion, cooking and reading. Quite frankly, I think it would be a bad thing if he didn't do any of those things, lol. As a transwoman, I remember what it was like to have the social pressure to be one of the guys when I had no ability to do it. It's hard and unfair how rigid society expects boys to act (women get it as well of course). Don't let it define you. You are you first. An unique individual who happens to be a specific gender.
