TMI! Always feel like I can orgasm twice or more?

This is only when I masturbate , cause when I orgasm during sex I sometimes need a few minutes or just wanna go one round. But when I masturbate , oooooooh lmao if it's a really good orgasm I sometimes don't wanna stop and have another one, is it possible though 😂 like I think it happened once but the 2nd one was EXTREME 😂, Im embarrassed that Im 18 and didn't know my body can do these things, I was never actually close to my body as I have been lately.
