I need advice... the man I live with for two years can only ejaculate if he masterbates... I am very frustrated by this because he has never ejaculated inside of me duriong sex, he can only climax with his own hand... I have tried oral sex until my mouth hurts, and still nothing from him... When I try to approach him in a loving manner, he clams up, does not want to discuss... I truly believe that he has done this for so long that the only thing his penis knows is the masters hand... Any advice?

Yup.

Get him to stop masturbating for about a month.

He's so used to himself that nothing else works anymore.

Agree... the man has been way too into himself for too long. He needs a long term separation from Rosie Palmer and her sisters.
