[/INST] Degree understand your concerns went through your details. Erectile dysfunction (ED) or impotence is sexual dysfunction characterized by the inability to develop or maintain an erection of the penis during sexual activity. It may be caused by diseases, complications from surgery, side effects of certain medications, lifestyle factors, and psychological factors. The water comes out of your penis during your sexual arousal is pre-ejaculation fluid, which actually helps you as a lubricator while having sexual intercourse. Do not confuse or worry about that. I suggest you to consult a urologist or sexologist for further investigation and treatment options. If you require more of my help in this aspect, please use this URL. http://goo.gl/aYW2pR.
