I am 10 weeks since RP surgery and have been taking cialis 5 mg for about 2 weeks as prescribed by my doctor. I have read on the forums about these drugs and injections that everyone takes to get an erection for intercourse and increase blood flow. I have not been able to have a usuable erection yet, even with extra stimulation from my wife. I have 2 questions. If you are using injections or drugs, and you get your first usable erection. Are you able to continue to have a second orgasm after the first one if, you still have an erection? Also, other than the drugs, what other means are best to get stimulation.
