Dating older guys

Caiti
Okay so I'm 17 and this 23 year old guy hit me up at work, things kinda just clicked so I've decided to give things a go, I then find out he's got a school girl fettish. We haven't met up yet and I'd just like some opinions 1. Is the age gap an issue, 2. I think his kink is a bit weird and does anyone agree?
