Sex help

Okay so me and my boyfriend have been sleeping together for maybe a month and I haven’t been with many other people and I’m just like nervous that I’m doing something wrong or idk. He’s older and has been with a lot more people and I don’t really know what to do so I’m not on top a lot. But we were talking with our friends and he said he doesn’t feel comfortable talking to me about sex because I’m so young. And then I made a joke like I’m not giving him head for a while cause I was mad at him and he said all I do is lay there during sex anyway. Anyway I want to do more now so anyone have like advice or know if videos I could watch for educational purposes?
