How do you orgasm from penetration?

Kathrina

How often do women have orgasms from sex penetration? It’s also really hard for me to finish because of how intense the feeling is before reaching an orgasm. It’s very overwhelming and overstimulating. But that only happens when the clit is involved and not through penetration. I know there’s such a thing called the G spot and I guess that’s how you would reach an orgasm through penetration, but I have no idea where my G spot is.
