Unlike what you see in the movies--30 seconds of intercourse fowllowed by a simultaneous orgasm MOST women do not have an orgasm during intercourse alone--there is simply not enough clitoral stimulation while the whole penis is stilated for the men. Make sure your husband makes your come once or more before intercourse with oral sex and stimulation of your clitoris and G-spot with his fingers, then explore different angles when you  have intercourse. You can also masturbate in front of him and then guide his hand to show you what you like.
