Sometimes, for like a week at a time my bf wont cum at all no matter what we do. Before he used to cum pretty quick, which i didnt really mind .. he lasts as long as he wants now but cant cum half the time. HE said it happened with his ex a few years ago too.. i asked him if it had anything to do with me and he said not at all, it's just somehitng that happens. Anyone ever hear of anything like this???
