Yep. You're confusing incontinence with impotence.
I had my RP last September & I'm still incontinent.

It's different for everyone, so there's no right answer.
Kegels should help - but in my case, I couldn't do them at all, even after 6 months of physio,
My understanding is that they wait at least 12 months before considering corrective surgery.
That's to give it time to get better on it's own.
They gave up on me - I'm having surgery next week.

So the short (and unhelpful) answer is that it's different for everyone.
But don't be shy about letting your urologist know that it's just not getting better and it's affecting your quality of life.
It's certainly better not having surgery, but it may be bad enough for them to ignore the guidelines.
But we're always here to vent to, regardless.
