I am realizing this now but when ever i masterbate my head even with lotion i get red on the top any of this its probably cuz its getting irritiated or something
Everytime after i masterbate
Well, are you washing it properly afterwards?
You may be doing it long enough or hard enough to irritate the skin. The lotion you're using may also be a problem. It may be getting rubbed into abrasions caused by the stroking. And you might be allergic to it.
