*edit for accidental UAV so, I'll just quote Dave, since he said it so gracefully
|As to circlist, look at the site thoroughly and you will more than likely conclude that is it not a reliable source of information.
It is perfectly normal for your son not to be able to retract now, regardless of past retraction.
Even if there was scar tissue from the retraction as an infant, some studies have shown the scars usually release themselves if left alone (somebody got that link? ) Basically, the glans and foreskin repair that original bond and release later (kinda like if your fingernail rips off, it builds that bond back again, bada-bing, happy new fingernail)
If your son is still not retractable AFTER puberty, steroid creams may be prescribed to help loosen things up. Stretching exercises can help. If there is scar tissue (called adhesions or skin bridges), a doc can snip them. By that time, your son will be a young man and will be able to make decisions for himself.
But, as long as he can pee, let it be.
