Transsexual? Transvestite? Transgender? What does all this mean?

How can I know which of these labels applies to me or someone I know?

Can these gender issues be cured?

Why are you a transsexual, Christine... or anybody else for that matter?

So, do you like guys or what? Are you gay?

I'm more than reasonably certain I'm a transsexual, so what do I do?

Christine what hormone regimen do you/have you used?

How did you prepare yourself for surgery and SRS in particular?

Christine what about sex? Can you have an orgasm?

What if my question isn't answered or if I want to learn more about gender?

Where can I find a trans-whatchamacallit for SEX???
