Can a guy really go without cumming

I made out with this guy for atleast a hour and a half and we’ve been talking about having sex but we were in the car this time so we literally just kept making out. It was really good and he was literally shaking like his legs would not stop shaking back and forth and i just kept waiting for him to ask to do it and ik he was definitely hard. Can’t guys not go on like that without cumming cause don’t they get like pain ? i’m just curious lol 😂 😝
