Is it normal that i feel attracted by having multiple genders?

I've been living a distorted life for quite a few years because of depression and problems related to sexuality. Today I'm going to focus on the sex topic.

Generally, I like to wear clothes that makes me a ambiguous person. I've heard a lot people saying behind my back "Is it a girl or a boy?". This always made me feel happy and aroused, but nervous at the same time because I don't like to lie and I feel this will only bring terrible consequences in the future.
I have one friend (which is a lesbian) that like the fact of me having a weird identity that almost nobody knows correctly. Sometimes she calls me by a boy's name, others by a girl's name, making me smile and feel excited.

After a few years, I started to question myself "Am I a liar to myself? Am I a crazy person, or it's just a fetish? Why do I keep denying my body?".
I didn't reveal this to my family, and I pretend to say nothing about it until my parents die (or when I stop living in the same country as them). When I'm alone I like to imagine fantasize myself being both genders but at the same time being none of them. There was a few times when I was alone in my home I tried a few clothes from my father (even though they're too big for me) and another ones from my sister. I tried wearing his underwear and no bra, or wearing his shirts and ties. After that I took my sister panties, bras and dresses to change (even if I have mine own collection of underwears and bras, she have the prettiest ones).

Sorry if is not well explained, but for me it's really hard to talk about this situation. I hope you guys understand what I'm trying to say.
(P.s.: sorry for the bad english. It's not my mother language.)
