I have problem of pennies skin opening mouth shrinkage. When, not erect, skin can be easily pulled back, but when full erect, it is difficult due to skin mouth is narrow. It do not happen day today, but automatically gets ok and again repeats after some days or months. It feels very dry skin of pennies and when pulled back by force, it gets turned at the circumference of opening mouth and swells, being difficult time thereafter. Because of this, I do not dare to have intercourse, and wait for automatically fixing of the problem for few days. Please suggest.
