Am I still wet or did I come?

So late last night me and my boyfriend were going at it and I’m naturally really wet but sometimes I can’t tell if I’m just wet or if I’ve came yet. He’s the only guy so far that has actually been able to make me cum and sometimes I don’t realize it. How do you know if your still just wet or if you’ve came yet? Or am I just the only dumb one on here😂
