How do I tell my girlfriend I'm sterile?

I am an 18-year-old male. And I lost my ability to reproduce in a bull riding accident at a rodeo I competed in about two years ago. I would like to father children more than anything. And now I have a girlfriend who is talking of wanting to have kids in the future. But I can't bring myself to tell her that I can't because I still haven't dealt with the problem of coping with it myself. I need to know how to deal with the fact I cannot have kids, especially now that my significant other wants them, but is ignorant to the fact that I am sterile. Please help me ASAP! This is tearing me apart.


How do I define my sexuality and tell my parents about my transgender partner?

I am a girl, in love with a transgender guy. He was born with the wrong parts, but is truly the kindest person I have ever met. I love him very much, but I am afraid to tell my parents. "Adam" may have been born a female, but he is now a male, and is planing on getting surgery to prove it. My parents are Christians, and I'm not sure they will approve of him. Does me liking Adam, and female to male transgender people, make me a lesbian? Or bi-sexual? My parents deeply disagree with these things and I am afraid to talk to them about Adam.
