Welcome, Laura. Know that you are not alone and many of us experience(d) the same thing. Now science knows it is largely biological and there is nothing you can do about it. So,the trick is to learn to accept yourself as a natural wonder. I'm feeling out of sorts today but tommorow or Monday I'll try to email you some URL's to read more at some good web sites that explain transgendered people better than I could here. We are tremendously varied even in the transgender community. Here you will find friends, helpful sisters, learn about yourself and how to be better at being whatever kind of TG person you discover that you are. You might try reading some TrannyBlogs and some Forum threads to get a more personalized view of our community.
