My boyfriend and I have been together for a little over 2 years. In the past year we have really been opening up our sex life and trying new things. We have gone from the most basic vanilla to pegging, beginner BDSM, collars, chains, and we even went to a sex party. He loves being my submissive, my little, and sometimes light puppy play (a little new). And I love being a dom. I love the power and the knowledge that I am pleasing him. But I don't feel confident in what I'm doing. I never really know what to say or when it is ok to move on to a new scene. I'm hoping for some advise from either subs or doms on what you guys have said or tried and what has seemed to work. 

Much Appreciated,
A Hesitant Dom
