For some reason im having a hard time thinking about how that conversation went down.
"Yeah i want to have sex with you for sure, but.....If you cant make me cum 3 times im just not gonna fool with it"
i dont know, just sounded kinda funny. I would say try masturbating and when you feel that you are close to climax try suddenly switching it off in your mind cause thats all it takes really. Just learn when you need to take your mind off it and when its just too late and youre gonna blow.
