My boyfriend's balls are more sensitive than most. His are very fragile for some reason. Sometimes we can't have sex cause they hurt even from light banging. Another guy even told him that he bet his balls are very fragile because he doesn't drink milk. Does milk strengthen for some reason? What is in milk that would do this? Is it Calcium or something else? Could he take calcium pills instead to get them a little more non-fragile. Is he going to be like this forever now or can he change the situation so we can enjoy each other more often.
