Why do guys like to makeout so much?

a few weeks ago i was making out with this guy at a party for the longest time and it was like 11 pm and i was falling asleep on him and he kept kissing me and kept trying to get me to wake up and keep making out like he wanted to do that alllllll night. A few days ago i was making out with this other guy and he would stop and say something quick and then be like where were we and his short beard kept scratching me so i had to keep stopping but he didnt seem to like the interruptions and before he had to go he was like one more good one and would keep saying that. I mean i like making out but im not like how they were.... im just wondering why are guys like this? please be nice! thanks so much!! :)
