Me and my husband have been married 7 years we have 4 children, he has always been less interested in sex than I he is satisfied if we have sex only 1 or twice week, and as we had more children his interest in sex decreases. Now when we have sex I always have orgasm before him and sometimes he can't, does this mean he has problem or am I the problem. He is 37 and I am 30, and he is healthy.
