I was giving my boyfriend a hand job while I was doing that he told me I ripped his foreskin and it hurts so we did not do anything for a couple of weeks after that his foreskin got very hard and rubbery. If I pull his skin down he tells me that it hurts and the skin will not go down it has a hard ring at the tip of his foreskin. What should I do to make his skin soft and not rubbery?
