I looked up on web MD. and other sources about the chastity cages for cocks. They say that if a cock is prevented from having the nocturnal erections that is natural you can ******* his cock and cause impenitence so he will not be able when released to get hard. ....
Nonsense. There have been no studies regarding long term use of chastity devices and there is little information regarding any problems related to them.
The only known issues are regarding proper sanitation and fitting of the devices as too tight can cause compression injuries, which are minor such as bruising and soreness.
Some men note that they reach orgasm quicker when released, but that could be due to being extremely excited at the opportunity to orgasm.
There is also mention of "congestion", but it is rare and occurs in men who don't use any form of chastity device. Additionally, extremely frequent ejaculations can also create problems in a small number of men.
If there were any negative effects from long term chastity use, by now there would be reports and studies documenting it, especially by urology specialists. There aren't any.
At least none that I can find, google or otherwise, nor have my doctors ever heard of any problems. They are aware that I wear a ring without a cage and we have discussed the subject as my Wife considered having me wear a device and wanted to know if there were any problems related to it.
Her reasons for abandoning the idea were primarily because she found out it would be more work for her to keep me locked up.
In any case, if you are going to make a claim that you read such a thing on a verifiable website, please provide the link to it so that it can be investigated for accuracy and validity.
