What does a guy mean when he says "we should mess around"?

So a guy I just met (he was asking around about me before I officially met him) seems to be really interested in me and he's nice and everything and seems to be interested in being in a relationship, but I don't know that much about him just yet. We were texting and he suddenly brings up "are you a virgin?" and I said yes why? and he replies with "just asking we should mess around haha" so what exactly does "mess around" mean?

I replied with (my friend advised) "wth do you mean by that?" but its been almost an entire day and he won't repond, and I feel awkward to text him anything if he won't even answr that..
