EXPLAIN! Orgasmic tips!?

I have had my share of encounters in my active adult life, and now I have a man that I truly love, and care about, but I'm 100% sure I have never had an orgasm. With him, or my previous partners, and that's something we both want in this relationship. There is definitely an extremely strong sexual attraction, but what are some tips to help us to the explosion or ways to get close???
