The Cialis/viagra has given me the opportunity to wake up but does not give me a good solid erection with whats left of my penis. I also found that it was easy to loose it. While I found enjoyment in the foreplay my penis would take a break. C&V only work with stimulation. I dont know since it didnt work well for me, but I think having an orgasm would end it. I have gone to using trimix. Erection lasts about 2.5 hrs. The erection will last whether you orgasm or not. I suppose multiple orgasms would be possible. I figure what for? I have found it to be much harder to orgasm than in my previous life. My partner is waiting on me. Then I have issues with sometimes I get fluid with my orgasm(urine leak). I feel really lucky to be able to get to this point with my manhood. The whole process of sex with your partner is not the the relaxed activity it was in the past. To go for another orgasm would be sort of a marathon that I am willing to forego until another day. I know my partner is. My RP was 6 years ago. I did not get an erection until 5 years with Trimix.
