Ive been looking into it and found out what the red line on my penis was that goes from the tip of the penis to the anus getting wider at the very bottom of the undershaft of my penis then straigh skinny line through the scrotum. I am only 15 so I am having troubles knowing what to do? girls at this age wont understand and if it got out imagine what type of drama can start get out around highschools.... My question is, is there anything you can do to lessen the darkness of the red lines?? and what do other guys with noticable penile raphes tell girls and what not... any info will help alot thanks.
That red line is the perineal raphe. It is normal and everyone has one.
Girls also have a raphe. I would not worry about it.
