Hi and welcome to the world of BdSm. I think you'll like that new world.
In any relationship comunication is very important and it certainly is even more important in our world.
Being a quite experienced Master myself. I find communication very important. Especially with a new and inexperienced sub like yourself. As it's the only way to know about your limitations. You'll have to say what you liked and disliked and what you wants more or less of.
So even though we dominant males can be very ignorant (Just as female dom... Male subs and female subs) Let him understand that you need to talk about your new experience and what you felt about them.
Wish you the best of luck.
