As already pointed out, everyone is different and I think it goes without saying that any pre-surgery ED issues will not be remedied. I can honestly say for the first 12mths, there was nothing, it was limp, nothing. 18mths on a lot of improvements, particularly with the pump, I don't the daily 5mg tadalafil, get 8 tabs of 20mg on prescription and meant to take 3 a week, some weeks I don't take any and some weeks I manage to. However I noticed, I can manage an erection if I take it 3ce in a week, but I have to be stimulated somewhat, not just get an erection for the fun of it!
My darling wife is going through menopause, sadly intimacy and sex is the last thing on her mind at the moment, so I have no desire or urge to take the tablets or even exercise with the pump.
