My problem is that since last month I ve a tight foreskin, which when erect doesn t pulls off the penis. & if I try to do any sexual activity it is painful, the skin cracks & burns like hell. in normal condition the skin can be pull off slowly but not as easily as it use to be, under the skin over the penis head there seems some white thing sticked to it, which after washing goes off, but comes again next day. I am unable to perform regular sex due to this, please help.
