Am I exaggerating?

Okay so yesterday I was at my boyfriends house for the whole day. We got down to business (if you know what I mean 😉) for pretty much the entire day (with little breaks) . After we were done he kept wanting to sleep because he said he was tired so we cuddled up but ended up doing it one last time before I had to go, everything was going great. But as soon as I left his friends come over and he's ready to continue the night. This bothered me because he said he was "dead" and I thought he would go to sleep after I left but instead he invited his friends over and his tiredness was all of a sudden gone. Should I let it go?
