Too Shy?

Alright so me and my boyfriend have been getting very frisky the past couple of times we have seen eachother, and we haven't been together for too long but he is one of the Freaky types, he likes to do all different things and me I don't know if I'm just not comfortable with him yet or if I should just go with it and try some of the things he wants to do. I don't want to kill his vibe but also don't want to do something wrong and completely embarrass myself.
