bf intimacy help!

so my bf and i have been together for almost 3 months and friends before. but he's not a virgin and i am. so he's just more experienced than i am. this isn't a problem for me because i don't want sex. my problem is that today while making out he kept touching my butt and stuff. does this mean anything? i don't have a nice butt or anything, pretty average. does he want to go further? or is this just him being affectionate? advice please 🙏
