HELP PLEASE

So im trying to find the right moment or scenario to ask this guy if he is or has ever dated anyone but I dont know how to bring it up.

Heres what happened today in our orchestra lesson one on one today:

A quick rundown that I sent to my friend

“Oh my god hes so beautiful up close, anyways it went pretty good he was very helpful, but I think he was lowkey scared. He also knew who I was in the musical which is so tuff. I didnt get to small talk because we like did a lot of music but he said text him if I need more help so im gonna ask to do it again and try talking more, we laughed together a bit at the loud classroom but overall hes really sweet”

As you can tell its already going good but I genuinely dont know how to bring it up.
