My girlfriend an I have been together for about 5years. We had decided a year ago that we wanted to get pregnant. we have been trying, and trying. it seems like nothing is working. I have noticed every time I ejaculate into her, later on the cum just flows back out of her, an in her panties. I feel really bad, and sort of embarrassed. Please help me to see if this is normal or what else I can do. We have tired different positions, and it seems like are ideas don't work.
