He felt empty...

My SO and I have been TTC for 2 years now and haven’t had any luck but we still continue to try. The first time we had sex this cycle he said he felt tingles in his sack and it felt empty. I laughed so hard because like DUH. But he’s never said that EVER. Like, he’s never had that feeling before. Then again last night he said the same thing after sex. He felt “empty/drained”. Not like emotionally or physically but talking about his ball sack. 😂

Has anyone else’s man said that after sex?
