Hooked up with a coworker/friend...

I️ve been friends with one of my coworkers since he started at my job. I’m 21 and he’s 24 and we both work at a restaurant as a part time job during school. He has a very flirty personality to the point he’ll tell people at work we’re dating or that he’s bought me things people at work have complimented me on. This has been going on since he started so I’ve gotten used to it and never liked him more than a friend. He flirts with me so much people tease us about having a thing together and going on dates. Recently, one of our friends had a party and a bunch of coworkers and outside people were there. We ended up in the same bed at the end of the night and hooked up. The next morning I️ had work and remembered what happened and I️ was okay with it. Actually I️ was surprised but being with him felt natural and we were laughing like goons, it was fun. It’s been a week now and I️ can’t stop thinking about him. We haven’t really talked just Snapchat here and there and he texted me the morning after and asked how I was feeling( bc of being hungover) and I️ jokingly said I’m really tired thanks for keeping me up all night and we laughed about it. Idk if I️ like him more than a friend but I know for sure I️ want it to happen again. He’s such a cool laid back guy and I️ feel comfortable with him. My friend who didn’t go to the party asked who I️ hooked up with that night and asked if it was him without me even saying anything to her. She said it’s our chemistry that gave it away for her and it seems like we’ve done stuff before. In the back of my head I️ like him but reality sets in and I’m not ready for a relationship. Commitment freaks me out. I️ get butterflies when I️ see him now which never happened before and I️ don’t want our friendship to be ruined but I️ find him sexually attractive now which I️ didn’t before this happened. Idk what to do.
