Hi, I have a seminal fluid leakage problem. Whenever I think of something arousing, the fluid starts to leak from my penis . And when I try to indulge in foreplay, I get an erection once in the very first time and then with in like 20 seconds it starts to sag and I am not able to bring it to a proper erection afterwards. And the seminal fluid keeps leaking and I get very tired with in a short duration. I have consulted a doctor before and he prescribed penegra 50 mg. I used it once and I was able to have a proper sex on that day. I dont have any noticeable heart problem and I smoke heavily. Off late even without thinking about something arousing, this seminal fluid leakage happens. Can you please suggest me the proper solution for this?
