Age? Or...

I'm 25 & started going to school again taking my basic required classes at a community college near my house. I met a guy there and we clicked and hit it off immediately.. Everyday after class we meet up & hang out & talk .. So he told me he likes me and we start asking each other questions I figured he was younger than me but when he told me his age I really didn't know it was that young.. He's 19 & I feel kind of weirded out by that... He says he likes older girls and the age factor isn't a big deal.. He acts way mature, he's taller than me, muscular I would of never guessed.. How should I go about this? Would this be wrong to even try to be more than friends?
