I very much agree with what has been said already, so I'll refrain from repeating it all over again

When I first started out in the lifestyle (sounds strange to me, but will have to do) we were both brandnew, he a little more than me (insignificantly, really). We were vanilla, something happened (what -- don't ask me) -- and suddenly we weren't anymore. What I'm getting at is that in the beginning he was very careful with me, and very nervous to unintentionally do something I didn't enjoy etc. Giving positive feedback was really important. I did all the moaning and 'please more' stuff that has already been suggested, but I also made sure that he knew that I really enjoyed our activities a lot. I wrote little notes, saying things like "I loved it when you <insert activity of your choice here>", or similar. He liked that, I think, and he got bolder with time. Building trust works both ways. I believe it was easier for me -- I knew he loved me, and I knew that if I used my safeword he would stop right away. However, he had to trust me as well. He had to learn to trust me that I wouldn't run and shout "Police!" once the arousal wore off. He had to learn to trust me that I *would* use my safeword if I needed to. And oh, it was an exciting and very satisfying time -- I almost envy you a bit I'd say, enjoy and let things develop with time...and before long you'll most likely end up with a bit more than you bargained for (yes, they have a tendency to get MEAN once they know you like that)
