Recently I had a talk with my partner and he brought to my attention that I nothing ever comes out when I have an orgasm. Is this normal for a woman to have empty orgasims?

Just because you don't run like a water faucet doesn't mean that things aren't happening. You are unique. Every woman is, and none of our orgasms are the same.

Yes. You are fine, healthy, and having orgasms. Nothing needs to come out. Period.
