Hey is this a normal sexual thing.

Al
My guy doesn't really cum when we have sex. He just wants to have sex so I orgasm. In the past month of us having sex ( which was about 5 times a week a guest-a-ment). He's only came about 5 times. I feel like I'm doing something wrong. He wants a baby, but How can we if his sperm aren't inside me. Any ideas?
