How am I supposed to ride his dick?

Heyyy I just lost my virginity last month and I've had sex with two guys in total. I tried to ride the first guy but like I couldn't put it in myself and he kind of just ended up moving. The second guy, he asked if I could ride and I said I would try but I couldn't put it in myself 😭 I assume it's because I'm not experienced enough yet but I'd like to be able to ride because I don't always wanna let the guy do all the work 🙈 Has anyone got any tips for me to try???
