The Global Survey on Circumcision Harm is a great resource to go to when researching the harm that circumcision does. If you are circumcised, I strongly urge you to take the survey.
On the site are also photos of the harm this "procedure" does. I feel I must share one of those photos now, here, with you. I will say upfront this photograph is NSFW and may not be appropriate to younger viewers. This photo will upset people, as it *should*... because this was preventable and shouldn't ever happen.
Again, allow me to repeat: THIS WAS PREVENTABLE AND UNNECESSARY.
I've been asked to clarify what the text says because it is very small print. Here it is:
"My parents wanted me to be cut because they are religious people and thought uncut atheists were bad people. The cutting was not very good and this is what I have now. I suffer because of my cock and I'm virgin.
"Dats all.
"Don't cut babies. Don't forget the risks.
"Let them choose when they are adult. They must have the choice."
(Capitalization and punctuation were corrected by myself for easier reading, but I did not change his wording.)
