Never had a boyfriend before this is all new to me but when were making out and im sitting on his lap he moves his hips up and down aggressively?

even holding me tighter pushing me down i do enjoy it but i just wanna know what his feeling im kinda nervous to ask him we both never had a partner were each others first kiss and shit but does it mean his like hard or something is he enjoying it, he also becomes really aggresive with his actions whats the deal
