I just spent like ten minutes typing a reply and the internet ate it

Anyway. Your hair looks kind of similar to mine before I got it cut last so I'll tell you what I did. I got it cut really short on the back and sides so it's completely off my ears and neck, I also use a strong pomade to part my hair on one side and kind of sweep my hair off my forehead.
I also have an unnatural hair color (purple for me) and I'd agree that it doesn't help me pass, but I love it enough to keep it anyway.
I don't know if a fauxhawk would be feminizing but a mohawk probably would be because it would show off the shape of your head. If your head is more round than square it will look feminine. Also mohawks seem to be very popular with women right now. Most of the women in my line of work seem to have mohawks right now.
Edit: And one other thing I meant to say. I think my haircut works well, but I still don't usually pass, hopefully for other reasons. It does make me feel a lot more like a guy, and I think that counts for a lot in terms of my self image.
