Hi slipknotshinji,
I think it's fine to have a variety of interests, including those that seem girly, even when you ultimately identify as a guy. I believe gender identity is fluid and on a spectrum, and that a lot of what we feel is 'boyish' or 'girly' is socially constructed by the society or culture we are in. Therefore, I think you don't need to feel pressured to fit yourself into one category or the other, but rather go along with what you feel comfortable with, or what you relate more to or identify more with.
It's good to think about identity, I would say it's even something that's fun and evolves as you grow and go through life. I think you'll eventually figure it out, so don't worry and don't rush it. Also, your thoughts about your own gender might change later as well!
Hope this helps. :))
