Have your orgasm before he enters you

This is especially good for men who come quite quickly. If he goes down on you (or masturbates you) until you have an orgasm, the pressure on him not to come quickly during sex is much reduced. What's more, making love to you after you've had an orgasm means your vagina will still be hot, wet and swollen, and this will be a real turn-on for him, not to mention the fact that it will feel absolutely wonderful for him when he penetrates you.
