Just curious: What exactly are "feminine thoughts"?

Your problem isn't your sex, that's simply biological and not something that says much about us at all. Your problem lies in the gender roles and societal expectations. You shouldn't have to switch sex to be who you are, that a man wanted to wear skirts or whatever shouldn't be frowned upon, because sex should to us be just that - sex, something biological that only means something in terms of reproduction, and not gender. The problem is that gender and sex are often mixed up, to the extent where people claim that this or that is a manly act/emotion or a womanly act/emotion etc. It just limits us all for being who we want to be.
