It's kinda hard to explain to people. I've been in this situation many times. I normally don't mention my "feminine" interests (as you put it) in conversation unless it comes up, in which case I don't mind discussing it. Just try to explain that just because you like some supposedly feminine things, doesn't mean that you're not a guy.
If you're feeling adventurous, you can try and do what Ron White did (proving that everyone is a little bit gay)! Man, that would be funny! (If you don't know, look it up)
At any rate, even if they don't listen, remember yourself that it doesn't make you any less of a guy. After all, gender roles are defined by society.
