Penis enlargement surgery is experimental, at best.
Lengthening surgery is probably better than girth surgery but you are required to hang after surgery and they have been instances, reported here, of people losing length. So why not just hang.
Girth surgery is another kettle of fish. Personally, I considered abusive of the surgeons to pray on male insecurity with such noxious options. If you are looking for horror stories for surgery, here’s one I am having the PE surgery done in 2 weeks. Girth surgery is far from a permanent solution, with fat implants being reabsorbed and other implants potentially requiring later removal.
It’s a shame in some ways that the quick fix solutions are so unpalatable. Breast surgery is a fairly mature field and though there have been some problems it is relatively simple in comparison, so that might be an answer in itself. So, you will find reputable surgeons do breast enlargement but those who do penis enlargement seem destined, as things stand to lose their reputation, which maybe explains why penis enlargement surgery is booming in countries with little or no regulation.
You’ve been registered since 2008, so how can you think that hanging weakens erections or that there are no permanent methods of gaining girth. There are people all around you who can refute that with their experience.
