Here, I will be honest. DON'T make a deal out of it. Masturbation is not dirty, it's not a bad thing! It already sounds like that's your goal. AND there's nothing wrong with removing the aid. AKA the Cinemax. We guys can be pretty darn creative in our minds. LOL! Now would be a great time to discuss how a man treats a woman and how to respect the opposite sex. Let him know those urges are natural and healthy too. Let him know you are there for him and he can come to you any time with questions. Yeah, be sure to throw some safe sex in there too!
