how to be on top??

so I've only had sex twice (my boyfriend is my first, but I'm not his first) and this morning was the second time. since the first time hurt, I was like "so we're going to have to do one more round of taking it easy" you know the pretty standard position before we try getting creative. he was like yea ok, makes sense. so that's what we were doing until he tells me to get on top. so we switch and I just sat there for a second and looked at him like… wtf am I supposed to do up here? so he kinda did it, I tried, didn't exactly succeed, when I would try he would take control from the bottom. it eventually got a little on the noisy side so we stopped that position and finished (well he did, I didn't) differently. we went to sleep and woke up later I laughed and was like "… whose idea was it for me to be on top" we both laughed about it and he was like "relax, you're still learning" but I don't really like thinking that I'm not doing well 😂 what are you supposed to do??? he said to use my hips, and when I thought I was he took over. from other things I've read on eve I think maybe a little more up and down ?? I'm tryna ride it like a soldier like drake said
