Vac hanging ugly dick syndrome

So after doing some reading I saw that van hanging can cause your dick to suffer from, for lack of a better term, ugly dick syndrome. Its said that heavy van hangers experience this. So my question is what is considered heavy? Is it those who use the most weight possible? Or those who strap in for hours on end? I’d like to know what leads to this. Anyone have any input here?

What makes an ugly dick different from any other? Its a dick, there’s a reason we don’t have any penis beauty pageants! :-)

Any more clarification on what you’re describing?

This is a excerpt from the hanging 101 thread:
Despite the great advantages of Vacuum hanging, there are still some downsides. You can’t go beyond 15lbs to 20lbs (compare that to a traditional hanger where there’s virtually no weight limit). At higher weights, the VAC hanger either causes too much pain or or the silicone sleeve tears (expensive). There are also reports that using a vacuum hanger for many years can cause a raised whitish circle on the glans. In fact, the same effect has been reported with extreme usage of VAC ADS Extenders as well. Overall, there have been numerous reports that VAC hangers can make your penis ugly. Based on anecdotal evidence, it appears this is more of a concern with heavy VAC hanger usage.

Hope this helps to somewhat explain what I am referring to.

I used VAC hanger for about 4 years and never had “raised whitish circle on the glans” that you speak of. Made decent gains from using this device but unfortunately it gave me some pretty bad blisters and just was not able to deal with the pain while hanging 15+ pounds. The main issue I had with VacHanger was preventing water blisters but surely liked how I was able to hang for 60 minute sets with this product. Also with the Vac, fatigue seemed to always be more prevalent than when I was using the BibStarter. Bib is great but still trying to figure out a way to prevent bruising and discoloration.
