Help!!! Do anyone know what it is ?

Yes, this is a common issue for Men, if this is what you mean? Relatively simple irritations such as this can have several causes - the most usual one is a reaction to a chemical the penis head / glans and foreskin are in regular contact with, anything from soap, shower gels, Lubes used for sex or masturbation, condoms that kind of thing .......

how can i treat it ? tell me please..

Sorry for the delay in getting back to you. I will post details below for all Men who suffer from these kinds of issues - NOTE, this is not aimed at treating you personally, it is to make you aware of the broader issues that may have led to what you have now, and, more importantly, what you can do about it.

Penile Hygiene Regime to Combat Specific Problems

The best approach is not to use ANY SOAP on the Glans / Head of your penis - wash with water only EVERY time you have urinated, after sexual arousal, and ejaculation. If you are not circumcised, protect the Glans of your penis every time you take a shower by drawing the foreskin as far forward as you can, then wash everywhere else, thoroughly rinse off all the gels / shampoo and suchlike, then expose your glans wash it with the water only using the inside of your hand, then each time you have washed it you must make sure to 100% pat dry immediately afterwards with a towel.

After you have put this in place and you still have the situation going on you need to look at what else your penis is coming into contact with on a fairly regular basis.  The likely suspects are:-

• any chemical compounds such as skin cream / lotions, baby oil, oil based lubes, chemicals inside condoms (e.g. easy-on and spermicides) you need to exclude these one by one to discover the culprit, the easiest approach is to exclude everything to start with, then once things are on the mend, introduce each individual item to discover what has caused this in the first place.
• if non of these make any difference you need to look to things such as washing powder in which you wash your clothes, and underwear in, in particular.  The simple alternative to washing powder is Liquid Soap Flakes, most sizeable supermarkets stock this in their own brand names - and you use this in your washing machine instead of powders or ANY fabric conditioner type additives.

  If all this produces no resolution to what you have, or your condition dramatically worsens, seek medical advice from your regular Doctor - but please note, many do not fully understand the differences between the potential skin conditions you may potentially have.  Therefore, the better course of action may be to see a Dermatologist, or alternatively, go to a Specialist Sexual Health Service and ask to see the duty Urologist.
