Welcome, Gray. Sorry you have to be here, but you'll find lots of support and shared experiences.
If your uro hasn't already discussed penile rehab, don't wait for a follow up appointment to ask him/her about it. If you didn't have much in the way of ED trouble pre-surgery, you're a good candidate to recover that function. Although it can take 1 or 2 years to regain natural erections, many uros now prescribe a combination penile rehabilitation program that can include daily Cialis (to encourage natural nocturnal erections), MUSE (intra-urethral), or penile injections (bimix) along with a vacuum erection device. The idea is to keep tissues oxygenated and to stretch your member .... sooner than later, to avoid atrophy and lessen chances for permanent ED issues.
I am not a medical professional. My surgery was May 21 and my doc already has me on Cialis and did my first injection today.
Here's to a GREAT recovery to both of us!
