So this is supper weird...

So me and my boyfriend had sex last night right before we went to bed. Big tmi he came in my twice like... wow. We both just ended up going to bed. I didn't get up just feel asleep. Once I sat up in the morning I didn't notice barley any cum come out. Just a tad wet on my underwear but barely. To me this is weird because every time he has once I got up it always come out like normal. Anyone have some thoughts ?
