Would you say that your body is appropriate for your system?
Within your DID system do you feel gender identity issues?
Overall, is your body agreeable?
Because these might be hard questions, I will remind the reader that no one should change their body through transsexual transition--unless the feelings are persistent for years, and there is no other way to be happy.
[For me, I never felt completely male, and I had ruined my life trying to be something that overall I am not. It's funny that even if I have male alters, I feel that overall I am female, and that is my gender identity. The male parts of myself understand this body.
Until I was hit by a car, I was pretty athletic: 15 years of daily Tai-Chi practice, a kempo lesson here and there, when I could afford it, I mountain biked. The male parts of myself, as well as my protector and its not-so-human counterpart understood that I had brought flexibility to the body while losing strength. It was the deal I worked.
Because I have a lot of autistic attributes, I am not strongly gendered. I have littles with either an androgynous identity, or no gender identity. Overall though, my body was not that masculine, and I feel that my body issues had a great part in your gender identity.
Still, I am not spared grief. There are many ways to present myself. And some days, are just closet emptying days, so bad, I've even gone all the way around to the first thing I put on : ) ]
