He needs to teach you and you need to find out what you like that is all. 6 weeks after starting having sex your gonna be shy once you find out what you like you'll be fine.
Now that whole all his ex's were virgins?!? Where did he learn all his moves? middle school, high school, porn?
I'm pretty sure if I was using the same moves that I started with I wouldn't be able to keep it up either.
