Men who experience such sexual dysfunctions as impotence or premature ejaculation may feel too embarrassed to open up about the problem to their partner. Keeping these feelings locked up is harmful, though---consulting your doctor about the matter and functioning with him on healing options will likely help cure the matter. 1. Priaprism. Priapism is a condition where a man has an erection that lasts longer than 4 hours. It is usually painful and not the result of sex plays. Having this kind of erection is not normal if you are going to compare it with the normal time span of the erection that happens in men. 2. Impotence. Impotence occurs when a man cannot maintain an erection long enough to have satisfactory intercourse or when he can't climax. This is the common problem for men, and thus this can also be considered as the main reason for them to have failed marriage, since there are some women who enjoy their partners who has the capability of giving their satisfaction sexually. 3. Libido. Men may experience a decrease in sex drive due to factors like depression or a deficiency in testosterone. The opposite side of the coin is sex addiction, where the man's sex drive is so overwhelming; it causes problems in his everyday life. This is the worst problem and sexual health issues if you can have this deficiency. It will be hard for you to control yourself when it comes to this stage being addicted with sex. 4. Peyronie's disease. Peyronie's disease can cause a lump to develop on the penis because of plaque that has accumulated within the erectile tissue. If this is left untreated it can be a big treat to anyone's lives. Having lump can be the start of cancerous diseases which may even lead to cancer. 5. Testicular Cancer. Men between the ages of 20 and 34 stand the most risk of developing cancer of the testicles. 6. Infertility. A man is considered infertile if he can't impregnate a woman. A low sperm count is usually the culprit with male infertility.
