Withdrawal, which is what it sounds like you are practicing in an odd form, is a very poor form of birth control with a high failure rate. If he won't use a condom, then you get a diaphragm and use it every time, or, better yet, go on the pill or get an injection. If you don't want a baby, use birth control. Go to Planned Parenthood, a doctor or clinic and they will help you choose the right method.
I agree with everyone else that his problem is having sex too frequently and, when you do have sex, he should be spending more time helping you climax. I suspect you'll like it. :)
