I know this thread hasnt been posted to in a while, but I restarted an account here so I am trying to get posts out there...
that being said, I am still pre-bottom surgery and would have to say I have noticed a great increase post pumping than I did in my first 2 years on t. Not just in size, both flaccid and erect, but also in blood flow. I have two very visible (when erect) blood vessels on either side of the shaft.
I am not saying it works well for everyone, I certainly remember when I first started it wasn't all that comfortable, but I have no regrets. Best of luck.
Oh and congrats on top surgery!
