Can’t orgasm

I’ve never vaginally orgasmed before, mainly because I haven’t tried. Last night, though, I told my boyfriend that I don’t care what has to happen, I’m gonna cum on his dick. Even after him fucking me really good and having the “feeling” of going to cum, I still didn’t cum. 😢 He even fingered me really hardcore, which is the only way I’ve ever gotten close to cumming vaginally, and it still didn’t work. I still had the “feeling”, but I never reached climax. Any advice? I really want to be able to cum on my man’s cock, for both mine and his pleasure. Any positions or anything like that that could possibly help?
