REALLY GOOD SEX

Yesterday morning I had sex w my fwb. I think sex w him is just so damn good. We hadn’t had sex in 4 months and I started off by riding him and it felt so good and everything was so good. But I didn’t cum, he ate me out and rubbed on me and fingered me but I didn’t finish. I have never actually had an orgasm w anyone else but myself. How can I make myself orgasm during sex?
