Clitoral stimulation is the key. Find it. Love it.
In sex, your (the males) pleasure and satisfaction is pretty much a guarantee. So since you know your pleasure is "in the bag" so to speak take your time and do LOTS of foreplay. Foreplay isn't for you, it's for her. Foreplay is VITALLY important to a woman. Women can take up towards 20 minutes to reach orgasm. Want to be a good and thoughtful lover? Make sure she has an orgasm before your penis even gets near her.
