There's no real way to be a man (or woman, speaking from the MtF perspective). You can be a man who identifies more with women. You can be a guy who is really effeminate. You can also be a guy who doesn't fit in with masculinity, and not femininity either.
Speaking as an MtF person, I don't really feel like a "woman" most of the time (because I don't really know that that would mean!). I don't identify with a lot of women, only a minority of them. Sometimes I even identify with men. I'm complicated, but so is everyone else.
What I mean is this: What you want your body to be like doesn't say anything about how you should act, write, speak, think or have sex. Being a man doesn't mean you fit any requirements, it just means that you are happy being one.
