Did this guy enjoy making out with me?

We talked and flirted before and started dancing at the frat house (not a relationship context). He turned me around and kissed me a few times while dancing then we moved to the couch and made out for 30 minutes. He kept tickling me and we were generally joking a lot of the night. He took his shirt off and helped me with mine. At one point he wanted to take my shorts off, but I didn't want to get into anything too much since I was a little tipsy. I'm wondering if genuinely he liked it or was with me because his friend wanted to get with mine. Would he have stopped earlier if he wasn't having fun? Thoughts?
