Well, it seems you have a lot of time to explore! This one is going to take patience, communication, exploration, and time. I've heard from a few men that there are basically two kinds of women when it comes to sex: Those that come from penetration, and those that come from grinding. While I don't know the exact truth of this statement, I have seen and been with both kinds of women. Some simply have to get on top and hit just the right combination of penetration along with clitoral stimulation. Since you don't way what gets you off during foreplay, I'll assume it is oral performed on you. If this is the case, there is a lot of direct clitoral stimulation. It is possible, trying different positions, to get both clitoral stimulation as well as vaginal stimulation from penetration. Try the top, try with you on your back with legs up so you can play with your clitoris, try on your hands and knees while reaching up and playing with your clitoris, etc. Your only limits are your imagination and your flexibility. Just remember the basic rule of sex: Orgasm is YOUR responsibility. Find out what does it, and share this information with your partner. Mindreading is in short supply, so speak up and get plenty of practice.
