Is a 9 year age gap in dating too much?

Darkstreax
I recently went out on a date with this guy and had a lot of fun. The only thing is I’m a 21 year old senior in college, and he’s 30. I met him at a bar and he looked really young for his age maybe like 24. However when we went out not only was it fun but he treated me so well, probably better than any other guy at my college has. Would it be bad to continue seeing each other even with the 9 year age gap?
