sex is sometimes a hard topic to bring up and speak openly about and since you're new to it, probably surrounded with a bit of anxiety. But talking about sex is really just like talking about everything else once you get the first few words out

like anything else, being open and commincating is the key to feeling comfortable with it.
To me, it sounds like you two might be ready for the next step in your physical relationship, but only you two can really make that decision. don't put too much pressue on yourself, just bring it up casually when you feel comforable and the thought occurs to you... but not when you're doing anything physical together, because then you both might feel pressured.
Just relax and bring it up, don't feel you have to 'wait for the right moment.'
Good luck
As a side note. And have you thought about what are you planning to use for Birth Control?
