Body doesn't know what it is doing

Ok so my boyfriend and I started having sex recently. Ive masturbated before just clit stuff and felt like I have orgasmed, just like little baby ones or something. But once I felt him inside me I realized that was wayyyyyyyyyy different and better than what I was doing. BUT it's so different and I haven't orgasmed yet bc I don't know what to do. It feels so good, but I don't know how to bring it to that point that I get to by myself bc it's just such a different feeling. He's super helpful and wants to get me to but I honestly do not know what to do. Any tips/tricks?
