Is it weird?

My boyfriend and I have been dating for almost 3 months, we dated 2 years ago for 4 months and got back together. I am 15 and he is 14. We have had oral sex and I still consider myself and him a virgin because we both haven't had intercourse yet. Even though none of this has anything to do with what I'm about to ask, I just wanted people to know the details.

I like it how when I bend over infront of him, to like pick something up or something, he grabs my waist and humps me like we are having sex. Basically dry humping. It makes me wet asf just feeling his body hit mine hard, and his strong hands grip my waist. He just does it for fun but I don't think he realizes how horny it makes me. Is this weird?
