Only something like 25-30% of women can orgasm from intercourse, so that's not really your best bet if you want to satisfy her.
But whatever your method, every woman is different. I've known women that take up to 40 minutes to reach orgasm, then they're totally spent. And others that will have 10 or 12 orgasms in as many minutes and want more. So if you're trying to please some special lady in your life, you need to learn what she likes and do that.
Good luck.
