The Bowel Cleanse certainly can't hurt, and will probably definitly help. besides that, tell him to never ever push hard (a clean bowel and enamas will make that less necassary)
One of the biggest weakness us men have is the he man theory that we have to push so hard. Tell him the toilet is not the place to read the paper and take a nap. when I'm in a public restroom and here men grunting and pushing, I gringe because I know from experience what they are doing to their plumbing.
Doctors tell men that 90% of them will get hemmroids by the time they are 30 and that's just a weekness in the human body. Bull****
that means our diet is bad and our colon is not working properly. I can tell you from experience if he does not address this issue, he will one day be bleeding down there and might get a "fisher" which is a tear on the inner wall. If he wants to test how that feels, tell him to put a bic lighter on his rectum for 4 hours. He'll then be beggin you to do a bowel cleanse.
