Are you wanting to do any of these activities? If you just don't feel like it, then it sounds to me like that's just who you are. And if that is the case, then don't worry about the thought others may carry about you.

Not being into manly things doesnt make you less masculine, it just means you have no interest in those subjects. I know plenty of men who by societies standards appear to be feminie, but are actually just as straight as the "jocks."

In my opinion, I think you should just embrace who you are, unless it's not who YOU want to be.

When you live tryng to be what you feel others admire for their approval, you're not living, you're just slowly killing who you really are, and that in itself is no way to live.
