He's not my type but I'm strangely attracted to him?

So there's this guy that I'm pretty sure likes me. It's really obvious. He's very kind and sweet. I'm really drawn to him but there's something that's holding me back. He's not very attractive. Well at least not what I find attractive. And he's also 9 years older than me which kind of freaks me out. I'm just not sure if I should "give him a chance" or whatever. Like what if he's the love my life but my stupid opinions are holding me back from giving him a chance? I've also never been in a relationship so I have like zero clues about guys. What should I do?
