So when my husband and I have intercourse I've noticed that after standing up for a little bit(maybe like 15-30 minutes later) his semen almost always starts coming out. I know it's it because there is a decent amount and the smell. But I was wondering if that's normal.

My second question is does it matter if we are trying to get pregnant? Because you need a little, just one sperm. So would it matter if most falls out?

Thanks in Advance!
