Welcome to Susan's, Frar.

There's a lot of good information and good people here. Each of our stories is unique but we have a lot in common. Settle in, pull up a keyboard, and explore.
Be sure to look under the Announcements heading. There you will find the rules we live by in this little world of ours: "Site Terms of Service and Rules to Live By", "Standard Terms and Definitions", and "Post Ranks". Look through the other stuff there, too, like "Age and the Forums".
As to your question, as the others have said: it depends. I am pre-op, which means that I still have all the boy bits I was born with. When I started blocking the testosterone and adding estrogen, I was asexual for a while. Now my sex drive seems to keep getting stronger. I hope it levels off at some point.

But it really depends on you and your situation. We all react to the hormones a bit differently.
