I personally found I never really cared to present 'masculine'. most my friends are women, I fit in better with women. I know for a fact that there is nothing wrong with who I am, it's just who I am and I should own it.

But I hear from a seduction perspective, many bring up "masculinity" as an important trait. but how important is it really, is my lack of it going to hurt me, or is it insignificant if I have everything else down?

EDIT: Added a missing word "Never"
