Point taken Doctor. Consider Psoriasis. Hydrocortisone cream 1% may help 'cure' it, based on my experience, and it could go away. I'm not talking about itch, btw.
Hi,
It is best that you get this examined by a doctor and thereafter get the tests done to find out the reason. It is not advisable that you try and solve this problem yourself as this may cause you even more distress.
Therefore I would advise you to take the correct measures and not try and diagnose the lesion yourself.
I would also advise you to use a protection device in all your sexual encounters in the future.
Hope this helped. Let me know if you may need any more information.
