A quick note that radical circumcision doesn't cut the skin around the dick. It amputates all the sexually specialized mucosal tissue intended to become one with the penetrated vagina. If you're circumcised it's tricky to understand the extent of the damages, hence why it's done to babies so they grow up never knowing any better. See hashtag circumcision for other videos where I've included informative links. I haven't vetted the rest of the video, but I'm assuming he knows what he's talking about on the other matters.
