Injections question

[Franklin22]

So I recently started with injections due to physchological ED that has pretty much plagued me my whole life off and on. Viagra was working fine and then with a new partner I would lose erection upon penetration. I went to see urologist and they gave me caverject. He stated that if I started injections I would never be able to go back to viagra again and would basically need injections for the foreseeable future.
Does anyone have any experience with being able to go back to viagra once you start injections?
My first experience with caverject was terrible. I had an erection for 6 hours.
I’m not sure if the needle stuff is for me. Considering implant .

I don't know why he would say that because it makes no sense at all. I've injected for a year and during that year took off from using Viagra, but now occasianly I'll use Viagra and it works fine of course with the sides. Many people use both for very long periods of time.
