bf not cumming in sex

Mia

been doing it with my bf for like a month

thing is I feel like he never cums like if he’s on top obviously he controls when we stop and when he does stop and like pulls out I don’t think there’s cum in the condom but I don’t know bc I’ve like never done it with anyone else

I mean I know he enjoys it he’s always rlly hard but I just wonder if I’m not too good at this whole thing

so how do I know if he cums in the condom what would it look like
