Socially awkward in bed?

Hi guys, I started to become more than friends with one of my best guy friends, but I’m terrible at being sexy 😂 we’re both goofballs but I tried buying some lingerie (he doesn’t know it yet) but I don’t even know how to be sexy..😩 we’ve hooked up and everything besides having sex. I just want to make things more fun, I haven’t had sex outside of a bed and he’s adventurous and has had sex and multiple fun, exciting places and has more experience. PLEASE GIVE SUGGESTIONS! no matter if it’s what you like or what your guys like. I’m going to be seeing him over winter break (we go to college together) and I want to make things special.
