Mental breakdown

So isn't best guy friend in highschool has always had a girlfriend, well we used to have little crushes on each other but we grew out of those. Well last night, we hung out & he talked me into staying the night(which I've done several times) well he kissed me & toldme he wanted to do that for awhile but was scared. We ended up having amazing sex, but I'm just so confused. Do you think he wants something more? Or was it just a spur of the moment thing😅
