I have nothing but female friends. I feel that I can only relate to them. I could never relate to males or stand them to be honest. But the problem I always faced when trying to be male is that females were scared or unsure of me. But when I accepted my female nature, things improved drastically, with a little work from me of course. I would suggest that maybe you try to reconnect with a female in your life that you know/knew. Send her an email or something. Facebook her. Just say something like this, lets pretend her name is Jessica too:
"Hi Jessica, this is (old male name), I know we were never really close, but I thought that perhaps you could help me. I know this is a stretch and I don't blame you if you don't want to be friends, but I'm now (new female name) and I am transitioning from male to female. I am going through a lot and would basically like a girl I could connect to and relate with to kinda teach me the in and outs of female socialization. Sincerely, (new nickname)"
Try this if you can. I've done it and it does work, for me at least. I promise you that if you put yourself out there some female is going to relate to you and want to help you and receive help from you (this part is important mind you). Thats what females do. I know it's scary, but you can do it. I can't begin to tell you how awesome it is to have girlfriends and just be able to talk to them about anything and to listen to them about anything. The risk is huge, but the reward is so very amazing. Please try this, and don't give up.
