Tips and ticks for sex

I just recently started having sex with my boyfriend. (Lost my virginity to him). But I honestly don’t know what to do. How to move. He’s usually the one that does all the work (thrusting). I’m just laying there as he’s going to town. When I get on top it’s the same, he’s doing all work. I want to be able to move how to move or what to do so I can pleasure him how he pleasures me. Please help. I try to move when I’m on top but I just feel silly and don’t feel like I’m doing anything to him or me.
