My boyfriend has recently confided in me that he cannot masturbate or have any form of sexual activity because of discomfort in the shaft of his penis at the rubbing motion (rubbing foreskin up and down).
He says its hard to describe but its like when you turn your eyelid inside out (strange metaphor!)
What can I do, or what can he do, to make sex and masturbation enjoyable? We both want him to be able to enjoy sex.
