When I had the ability to get an erection near-instantly all my life - for 70 years - I never had a twinge of a thought that "someday I may not be able to have sex." As a result, I never realized how tightly-bound my ability to have sex was with "being in a relationship." To clarify: Yes...I was married for 38 years before my divorce one month before my radical prostatectomy (RP), but...with the near-simultaneous divorce and RP which destroyed my ability to get an erection, I have been reeling in a frustrated depression about likely being alone the rest of my life, because if I have a relationship - even another marriage - I expect myself to be able to perform...to me it is the essential, necessary part of a man in a relationship: express my love and sexual desire with my girlfriend/wife. It came naturally...of its own volition...about six months ago, that "if I can't have sex and please my partner, then I am not going to "look", "date", or get serious about anyone." To me, it is the ultimate humiliation not to be able to perform. Forget "me" having the pleasure that I know I'd have...it is about my inability to please my future girlfriend or wife, that is the issue. I have been taking Cialis (Tadalifil) every other evening for nearly a year, with absolutely no result. I have heard and read about Trimix here, and my physician said that "when you're ready for it" he'll teach me how to inject it properly, but the word "inject" is a complete turn-off. I was around needles my entire professional life being the Director of Clinical and Anatomical Lab services in hospitals. I've stuck needles in literally thousands and thousands of people, but sticking one in my own penis is a "no go." So maybe the question to all of you guys is: How long did it take you to get an erection while taking Cialis? Next day, a week later, a month later, 6 months??? Knowing that will give me a chance to decide to stop taking Cialis, or to keep taking it because it might take two years. Thanks
