Why do guys sweat when they make out?

So its been hot outside lately and when my boyfriend and I were making out indoors. The room inside was pretty cool what with the AC going on, anyway he started perspiring to the point that droplets of sweat were rolling off of his face onto my face. I wasn't disgusted or anything, just surprised. Anywho, I responded by half caressing his face/ swiping back his sweat from his nose and other parts of his face towards his hairline. Do you think that was weird? I mean I didn't exactly want his sweat to be randomly dripping on my face (because it tickled lol) but I also didn't know how to respond to this. Why was he sweating? Should I have stopped making out and asked if he was ok or if he needed a break to clean himself up? I mean I don't want to be rude.
