Orgasms 💦💦

So, I was talking to a friend the other day and she was telling me about how she didn't know when she was younger that when girls are ready to cum it feels like you need to pee. I'm 20 and I've never had an orgasm from penetration cause I thought I couldn't, but during sex i get that feeling but I didn't think that was why! Girls is this true?? Someone help hahah what have I been missing out on 🙆🏻🙆🏻🙆🏻
