Weird question but..

Boyfriend and I had sex a few times this week. I can recall twice that we or he finished and I didn’t see any cum on me. He usually pulls out. Will cum on my stomach, boobs or face. Even if he cums down there, I feel it. But these couple times. He’ll sound like he’s cumming. Face looks like it. But I don’t feel any cum on me, after he pulls out and just lays down to fall asleep. Did he finish inside or maybe couple get off?

Just so this is clear. If we get pregnant that’s fine. I am just curious. Never actually had someone cum inside me. So don’t know if you felt it or?
