Dating an older man.

Samantha
So im 22 and hes 34. We met when he worked on my campus and I did work study and we're both single. I found him on FB and he added me as a friend. He messaged me and we went on our first date last night and had a fun time. I like him and he likes me, he stated we should see where this goes. He no longer works at my college, but my concern is the age gap. Any advice on whether or not I should keep this going or back off?
