Taekwondo Troubles

I just joined a Taekwondo class yesterday, in the hopes of losing weight and feeling better about myself. My problem? The owner of the dojo is 🔥HOT!🔥 I can't even describe how gorgeous this man is! 
So, I walked over to the front desk to ask him about registering for an adult class, and he REMEMBERED ME! 👏🏾😳🤗 
My other problem is that what if he likes me back? That might complicate my Taekwondo journey if we decide to hang out. Plus, I'm pretty sure he's older than me (#'90's baby)... Not sure if I should keep it professional or try to get his attention WITHOUT looking like an idiot, or worse, without getting blindsided and finding out that he has a girlfriend or that he's gay. 
I just want to find out what other people's opinions are. Thanks!
