I need advice.....

So i was walking to the gym when i relized i forgot my backpack in ELA. I didnt know my friend was walking 2 feet behind me so when i turned around i bumped into him and.... we kissed. It was on accident but ever since then he has been making googly eyes at me..... and i cant stop thinking about him.... when he touches my arm (which he does a lot) it feels like electricity. What do I do????!?!?
