Confront Your Partner's Criticism
When sexual functioning doesn't go as planned, how the partner reacts can make a huge difference. If they don't make a big deal out of it and are able to reassure the man that it's not a significant issue, this can keep it from becoming one in the future. On the other hand, a partner's belief that something is wrong, even if it isn't, can create functioning difficulties that weren't present before. Real issues with functioning down there shouldn't be ignored (and warrant a visit to the doctor) but being hypercritical can make mountains out of mole hills.
