I broke up with my girlfriend because I wanted to bang other girls
Are you serious? Why do you want to bang other girls?
It was a natural thought to me that I really wanted to do that.
It is best to break up with your partner if you want to have sex with other people. Because you should not cheat on them when you are still in a relationship.
Nah, I could just have sex with her permission.
I doubt she will give permission but you need to talk to her. You can't just go and cheat so you should talk to her or break up.
