Welcome to the club nobody ever wanted to belong to! We're all here for each other, and there's a gigantic amount of stuff on this site to digest. Plus, there's always the chat room.
Good job on taking the difficult step of finding a therapist. I've only had one myself for about 8 weeks, and I had to go through a couple before I found the right one. My wife and I were having lots of intimacy issues (related to my csa) before I started with my therapist and came to the MS site, so I have a sense of where you are.
Best of luck and again, welcome. You now have nearly 12,000 friends who all want to see you get past your csa and move forward.
If you have to rebuild yourself from the ground up, you get to do it the right way this time. And YOU'RE the builder.
