I'd say you're bisexual, but you lean more towards female. Maybe 75% female, 25% male? Anyway, you said the only thing keeping you from going any further is fear. What are you afraid of? What's the worst thing that could happen? The worst thing that could happen is you'd decide you don't like it, and then you'd know more about yourself. Maybe if you went all the way with a female it would answer some of your questions.

These are just my thoughts and opinions, they are not suggestions.
