Originally Answered: tight foreskin and how to make it loose for when erect.?
Please do not subject yourself to unnecessary discomfort. You do not need to stretch your foreskin, soften it, or any of the other things that people will suggest.
You do need to understand that some people can retract their foreskin and some people can't. You are in the latter category, and that is not a problem. Just leave it alone. It will not cause you any disadvantage in masturbation or sexual activity.
Do not do things to your penis that hurt it or can lead to permanent damage. The truth is that you do not need to retract your foreskin in order for your penis to function properly or to keep it perfectly clean. If your foreskin does not want to retract, just leave it alone. It is fine and perfectly normal like it is.
The foreskin does not have to be retracted at all. As far as I can work out, this myth originated in the USA, which is one of the few countries of the world to have ever had a chronic circumcision drive. They promoted what came to be known as the "clipped" look and told the world that it looked good, was good for your health, was cleaner, etc. If you have studied even the most basic of medical science you will know that these claims are not worth the paper they are written on.
Retraction of the foreskin is something that occurs in most guys in their adult years, but it still leaves many millions of men, particularly in Europe, Africa, North and South America and Asia and Australia (in other words - most of the world), who do not ever retract the foreskin. This number also includes men with what they think of as phimosis, whereas in most cases they simply have a foreskin that does not retract. Usually, in trying to pull it back so that they conform to the perceived notion that the foreskin should retract, they hurt themselves and, in some cases, rip the foreskin or the glans.
None of this is necessary. If your foreskin does not want to be retracted, leave it alone. It is quite simple to keep it clean and healthy without ever pulling the foreskin back. It is usually much easier to masturbate and to have sex without pulling the foreskin back than by forcefully doing so.
There actually are millions of men in the world at any one time, myself included, who do not retract their foreskin. I have a number of current patients in a similar condition and have, in the past, treated men in Asia and other countries with the condition of tight foreskin. Not one that I have personally met and not one that I have ever read about has a problem with cleaning. Nor do they have problems with masturbation or sex. And I have to join with them in saying that it is ridiculous to suggest that our penises are not functioning properly.
I repeat - you do not have to open your foreskin just because other people do it. Millions of men are just like you and never open it all their lives. Their lives are not affected by it, so nor should yours be. If you need lubrication, please be sensible and use a natural product rather than one that will cost you and may damage you permanently. Pure olive oil is the best thing to use in this situation.
