If not separated soon after the birth, foreskin may retract gradually. If it seems to be stuck without any ability to retract even when tried manually, you may want to see a doc and get some prescription corticosteroid to help release the foreskin ring (the opening) but a doc may decide to leave it like that and sees what happens.
Other doctors may suggest circumcision. Under no circumstances, should you accept this. This used to be the only method to get rid of the foreskin but today it seems to be the last option and personally I am against foreskin removal.
Try slowly retracting your son’s foreskin and if it is completely stuck, then you may want to see a doc. If it moves slightly, you should continue pulling it bit by bit every couple of days and see how it goes.
When boys are mature enough to wash on their own, you should show them how it is done. This means that you should show them how to fully retract the foreskin and wash under the foreskin regularly with warm water and mild soap, so that they could maintain good hygiene. Washing under the foreskin is very important.
Teaching boys to do this on their own is preferable, because they know how hard and how far they can pull it back without hurting too much.
Here is a related story. I pulled this message from another forum:
Re: Asian Foreskin Story
I guess they don't see (circumcision) as necessary. For
them it is normal that the glans will be uncovered
after puberty, so what's the fuss? And if it's not,
that's when they think about circumcision.
A close acquaintance of mine is south-east asian
by origin and he told me that he retracted his
foreskin just once - about age 12 - and that's where
it stayed ever since. To him that's just the natural
thing to do. Is it paraphimosis? I don't know and
never will - we're both married family men.
Note: My brother, cousin and I, and others we have met
or heard about later on, did the same thing. But some
of us think it would be better to start earlier, just
as soon as the foreskin is readily retractable.
Mothers, if for whatever reason you are going to delay
or avoid circumcision for your son, consider this cost-
less, painless and totally reversable alternative which
provides all of the same benefits.
Do him an important favor and help him get his foreskin
pulled back off the penis head at the earliest possible
This is all accurate - I have three sons - all with their foreskin intact and two younger brothers as well. All ranging in age from 18 months to 23 years.
This link will give you all the advice you need.
pulling back the foreskin of an immature penis is like peeling a green banana still on the tree. If you break the immature bond between the skin and the fruit, it may interfere with the development of the erogenous surfaces. If it is still bonded, why do you think that dirt can get in there?! Dont try and clean internals
There is great variation in the age at which a child's foreskin becomes retractable. The median point has been found to be 10.4 years. Your six year old is normal. No treatment is necessary. He does not need to retract his foreskin at this age.
Some boys do not retract until after they are into puberty. This too is normal.
Washing under the foreskin is advisable after a male becomes sexually active.
