Re: How about intact elderly?

First of all, may I congratulate you in keeping your sons intact, they will thank you in the future. They will be able to experience the thrill of having sex as nature intended it and possibly 10 to 15 years more than that of their sexually handicapped peers.
There are clear proceedures laid down for care the elderly (both male and female)

http://www.nocirc.org
have a brochure titled "answers to your Question about care of the intact penis in the geriatric/disabled population" this explains the simple process of looking after the intact elderly.
With your concerns of: as males age- the foreskin often seems to increase in length as the penis shrinks. It is also normal for the foreskin to to become increasingly resistant to retraction. These are natural aging processes and do not require treatment of any kind. Attempts at retraction of the narrowed foreskin cause unnecessary and unjustifiable pain and suffering. Thankfully, it is entirely unnecessary to retract the foreskin for hygiene. Using a bulb sringe, simply irrigate the preputal space with warm water.
I hope this information allays your fears which has possibly been brought about by the miss-information spread about by circumcisers.
They infiltrate columns such as this and play on the fears of the parents, at no time do they ever have the interest of the child at heart.
The best reference material you could ever lay your hands on is the book by Paul M Fleiss,M.D.and Frederick M.Hodges,D.Phil "What your Doctor may not tell you about CIRCUMCISION" This clearly shows the lies that are put out by people wanting to mutilate your boys. Remember there is not a Medical organisation in the World that supports circumcision
