Help w. My sex game!😩

I was having sex 2 days ago & in the middle of it he stops and he didn't want to have sex nomore. He said because I wasn't getting " wet " enough like wtf. Ever since we use condoms I don't get wet enough & I have started BC in July so idk if that has anything to do with that. Or maybe I just wasn't in the moment at the time idk. But he got mad at me & told me my sex game was weak. I mean he is my first I lost it too. I wanna try new things when we do have sex but I'm just sacred, like I don't know what I am doing. He does all the work and I wanna do something. I mean I gave him head before we do have sex & he loves that it's just the sex part. I still get shy around him and we've been talking for almost 5 months now. What should I do?😩 I need help.
