Sperm smell

Hello, me and my partner have been TTC. I noticed that my partner sperm does not have any smell to it. When I go to feel when he has finished I smell nothing.. most men I have been with have a chlorine smell. Second thing I noticed is when he ejaculates in me it does not drip out of me. It is almost like all of the sperm stays up inside me and never comes out.. is no smell and no dripping out of me normal?
