Corona glan of my penis is sensitive and red looking ? will i have to be prescribe with a cream?

Probably unnecessary: Mot likely, all what you have to do is leave it alone if having no long tight foreskin & feeling no local comfort but what you described or enhance local hygiene if having long tight foreskin and discomfort besides what you described. Yet, a direct look at to confirm what you described would be very helpful to deduce what should be done. More? Seek evaluation and counseling...
