Orgasm or not?

Celina • Hey ladies! I'm 18 years old and I'm on the app to keep track of my irregular periods and have a safer sex life 👍🏻❤️
Good afternoon ladies , I have a question so last night I had sex with my man for about 45 mins and while I was riding him I kept getting this feeling that I was about to orgasm but I didn't get that "relief" feeling after sex.. I still felt like I could go! Does that ever happen or do you know what that's called?
