If we’ve learned anything by now, it’s that everyone’s genitals look different. We may be pretty clued up on vaginas – from non-surgical vaginal treatments that could change your sex life, to what thrush really means – and we’re fully aware that each lady cavern is one-of-a-kind.

So in the same way that no two vaginas are the same, penises have their own little quirks too. Think of us all as having a unique biological stamp hidden away in the crotch of our pants. We’re allsnowflakes, people.

But bearing this in mind, urologic surgeon Dr David Shusterman has admitted that when it comes to male anatomy, there are four more common ‘types’.

Exhibit 1: The Big Head

If the head of the penis looks like it’s thicker than the body, then congratulations – you’re a Big Head. Dr Shusterman reckons around a fifth of penises are like this, so you’re in good company.

Exhibit 2: The Big Shaft

These girthy wonders work in the opposite way, with a much chunkier shaft slimming down into smaller head. Think chillies, or bottles and be prepared to never be able to drink a beer in the same way ever again.

Exhibit 3: The Curve

Another 10-20% of guys will have a very slight upward curve, and there’s actually a biological reason. Dr Shusterman told Buzzfeed: ‘There’s a suspensory ligament that holds your penis to your pelvis and it suspends your penis a little upward.’

He also explains that the majority of penises have a ‘north-facing bend of about five to ten degrees.’

Right guys, this is the one you need to be a little concerned about. According to Dr Shusterman an extreme curve (say between 30 and 60 degrees) can be a sign of Peyronie’s disease. This is caused by a buildup of plaque inside the shaft which then causes it to stiffen and bend.

It’s probably best to get down to your local GP, especially if it has an extreme curve when erect or has an hourglass shape.

So there you have it. Feeling smug about your wang knowledge yet? So tell me which one is you man’s.
