New man!!

I am with a new sexual partner, and I'm learning that there's a new sex language we need to learn. Is this normal? It's hard to read what he's thinking during the moment, and it's somewhat awkward to talk about it after the fact. The sex is amazing but I don't always orgasm. I think it's just because he's a new and different person. Im definitely excited about it! But I could use some help, tips, encouragement, is this just a phase?
