Help, I am confused!

This guy I somewhat had/have a crush on has been showing interest in me. Thing is, I’m happy being single right now and don’t really want to get into a relationship. Also, even though there’s chemistry and nothing feels forced I don’t feel sexual chemistry. I mean, I find him cute and everything, but I can’t picture myself kissing him or doing anything... But I also keep imagining scenarios where we’re a couple. What should I do? Should I go for it?
