Does a guy always get blue balls if he doesn't cum?

I was with this guy and we were doing the deed. We got into it and then he stopped because the condom had broke but he hasn't came yet. Since we didn't have anymore condoms he left and we were both unsatisfied. Later that day he told me that he didn't have blue balls even though he did not cum. So does a guy always have to get blue balls or did he cum and not know it?
