I touched his !!?

ok there was this guy me and him were hugging and stuff and we had been talking and cuddling and hugging and stuff for a couple of months. Then yesterday me and him were in a hallway together alone and he had his arm around me and he touched my he had been doing this for like 3 days straight so until yesterday i touched his . and he turned a little bit red and he didnt ask me to do it. I just did and i want to know what i should do when i go back to school on monday. And my friend said that she was surprised that we didnt kiss. lol. so what was he thinking when i did this. and what should i do.and they think that he likes me because before we would cuddle, sit on eachothers laps, he would give me piggyback rides. And then one day he licked my cheek and then after a couple of months i licked his hands and thats when this whole thing started. Now what? What should i do?
