It is totally normal to be into your feminine side.
What does it mean to be into your feminine side? Does it have anything to do with liking guys, girls, both neither, no it does not. You can be totally straight and be totally into your feminine side and feminizing yourself. You can be completely gay and have no thoughts of feminizing yourself. The fact is it has nothing to do with your sexual orientation and everything to do with what you enjoy and what your feelings are if you let yourself go and feel your truest self. That self is more likely then not a mix of male and female feelings, desires, emotions and self-image. That is true with every person we all are a mix. The question is do you let yourself be real and enjoy the side you might be suppressing?
