You reached a great place to express your concerns and get advice from those that have been in your exact position. I am 17 minutes post operative from a radical prostatectomy using the da Vinci and amusing a daily routine of Cialis, a pump three times a week to facilitate blood flow and overall mail hell and using bimix injections. The result is I have a pretty good Sex life with my girlfriend ..There is no doubt that it’s different than it was before.. But you have to realize this is the new normal if you’re committed to doing everything in your power To own your sexual health.. The rewards from the injections far outweigh taking a little shot!!! Best of luck brother.. Keep a positive attitude and roll with it!!
