We like each other. We're friends with benefits

We went to high school together, we lost contact when he graudated. (I'm 2 younger younger) I'm 18, he's 20. Anyway he added me on fb and we started hanging out and he brought up friends with benefits. We've been fine like that for a few months but yeah i told him I have feelings for you, he said he has feelings for me but could it even work being in a relationship ? Like we are friends with benefits. No judgement please. I'm just so confused
