let me try to tackle a different part of this equation. In my opinion, you should avoid getting a hard on while in a device. EG: no PE work while hard. Expect maybe in a pump, but thats a different convo. In most cases, the devices that I use prohibit my ability to get get hard, most of the time. haha.
So lets not worry with what you erect girth is right now. If your are 5.7 inches around in erect girth, you are doing good man. I had to get fillers to get there. But hey, good for you.
So . back to your original post, your focus right now is length. maybe some more girth later. So, in my own opinion, i would get busy on the work we have been talking about and do that for a while before any really invasive surgery that may not produce a good result. There are a lot of guys on here who have had ligs cut and much more, find them and message them to really get an idea if thats something you want to consider.
I don't know that you have mentioned, and please do not feel obligated . but if you are 5.7 in girth, i doubt you are that small in length. Just my 2cents.
We PM'd a little about this, but im going to say here too. I wear weights on my cock , or a stretcher, all day to keep tension on my dick. Weights are my preference , which are the most beneficial when standing. Im not familiar with sizemic and what he has worn, but let me just say this, if he was wearing golf weights and thats what you decide, They are far from concealable. Those bastards are 60mm wide. The ones i wear, i had custom made, and I made them small and out of tungsten. They are actually concealable
Your think that you are correct with your assumptions and plan of hanging and then using ADS. This should prove to be better than an extender as far as over all gains. Some people like extenders though. Maybe you will too, buy one if you want. but i dont you will need one.
