When your penis changes color, it doesn't sound great.
But you will be glad to know that in some cases it’s completely normal and there is nothing to worry about.
During sexual arousals, the penis can turn purple or red, it's just because of the extra blood flowing to the penis.
But if things don't go back to normal after the fun, it could be a warning sign.
There are a number of things which could cause the penis to change color so it's important to get it checked out.
- Penile cancer
According to the NHS website, a change of color of the penis skin or the foreskin could be a symptom of penile cancer. Men should also look out for a growth or sore that doesn't heal for a month, a foul-smelling discharge, thickening of the skin or foreskin or a rash.
