I am glad to find this discussion. Since my RALP (prostatectomy) 1 year ago, I have had very low libido and very weak, if discernable, orgasms. This has been most challenging adjustment. The pills have not worked, the shots give erections, but not a change in libido. I read about the tensioning device about 2 mos after surgery and have used it. I think I have reaped the benefit at this point, and only use it very occasionally now. There has been slow but significant improvement in erections and significant diminishing of the trimix dosage to a very low level (5 units at the moment.) I wonder what is yet to come....
And of course I'm grateful my uPSA still remains very low (last reading .012). If I had some of the more significant complications, I wouldn't be worrying about libido!
