Thank you to everyone for your replies.
I had my RALP surgery on 7/6/22. I am recovering very well and feel good. I was really pleased and surprised to find that I had full bladder control pretty much straight away after removal of catheter. I don’t know why it was but I was very grateful to not have incontinence problem.
I also found that when I’m kissing and cuddling with my lovely partner I still produce some lubrication which I assume must be from my Cowpers gland so that has answered for me my own question. It’s not as much a before but it is there and it works fine :)
No sign of an erection yet (I had half nerve sparing) but there are ‘stirrings’ in the groin and I am surprised that there is much feeling still in the penis.
