TWO types of penis have been defined by scientists for the first time.
Men whose todgers do not change greatly in size whether erect or flaccid are called “showers”.

A jump of less than a third gets a fella in that camp, new research states.
Meanwhile, willies which expand by 56 per cent or more are known as “growers”.
They also tend to be smaller when flaccid than showers.
Madrid-based Dr Manuel Alonso-Isa said the distinction is important for any potential surgery.
Professor Maarten Albersen, of the European Association of Urology, said while being a grower or a shower may have no medical consequence, the definition may still be useful.
He said: “This is a frequent area of concern for our patients and the emphasis should be on normalising baseline and erectile length for all.”
The average man in Britain measures around 3.4in when flaccid, previous research has shown.
But size when standing to attention has grown massively in the last 30 years, jumping from 4.8in in 1992 to 6in in 2021.
The latest study, presented at European Association of Urology (EAU) Congress in Milan, scanned 225 when they were flaccid and erect.
They found more than half of the men fit between the grower and shower categories.
A quarter were showers, while 24 per cent were growers.
Researchers found a part of tissue called the tunica albuginea which surrounds the penis became thinner for growers when they were erect.
