is it weird?

i was on top of my boyfriend with our clothes on (making out) and he grabbed my butt and started moving me forward and backward slowly and then he started doing it faster so my whole body moved on top of him and he was making faces while i was doing it and seemed like he was enjoying it. i’ve never done that before so is it normal for guys to do that or is it no big deal? it felt pretty weird at the time though lmao
