Crewneck or turtleneck? As you might have guessed, we aren't talking about fashion, we're talking about foreskin. And while nearly 80% of men in the United States are foreskin-free, in the rest of the world, foreskin is the norm. But for a such a small piece of skin, foreskin sure carries a lot of baggage. There are all kinds of debate about whether a cut or uncut penis is cleaner, sexier or more attractive.

And you know what? We aren't taking sides. Two sexy people who are attracted to each other should be able to have a great time, whether there's a foreskin between them or not. Even so, foreskin is pretty fascinating stuff. Here we look at nine nifty things you may not know about it.

It’s Found on 70% of the World’s Penises

If you've never seen a penis with its own sleeping bag, you might be surprised to learn that most penises come as they were made: all wrapped up. In fact, even in the United States, where most male babies are still circumcised, circumcision rates are dropping as public opinion about circumcision shifts.

It's a Built-In Masturbation Sleeve

All penises are unique (and awesome!), but if there's one thing to know about foreskins it's that it can make hand jobs a lot easier. By moving back and forth with the hand, foreskin provides protection, lubrication and extra stimulation all at the same time. Neat, huh? (Learn more in Sex and Circumcision: a Lady's Guide.)

It’s More Than Just Skin

Foreskin is actually a unique kind of skin that's more like an eyelid than the skin on the rest of the body. Foreskin also contains stem cells. As a result, foreskins have been used to cultivate skin and skin byproducts for skin creams, burn victims and cosmetic testing. Interesting. Although I'd much rather encounter foreskin on a familiar penis than rub a stranger's foreskin all over my face.

It Can Impact Female Pleasure

Most people who've had partners with both circumcised and uncircumcised penises will tell you that the partner matters more than the penis. However, foreskin does have some functionality in terms of female pleasure. Because the foreskin cuts down on friction, it can mean easier penetration and smoother glide, which can mean longer, more comfortable play, even without lube. (Although most people recommend that you use some anyway. Slippery is better!) The foreskin is also believed to bunch up and provide a little extra clitoral stimulation, which is never a bad thing.

Dildos Are Going Uncut Too

Whether you are into the feel or just the look of an uncut penis, that experience has typically been notoriously hard to come by in a dildo. Fortunately, there are some amazing uncut dildos out there. Some even have moving foreskin!

It Needs to Be Treated a Bit Differently

There's always a learning curve to getting to know a new partner, but there are few things to know about working with an uncircumcised penis. The first is that because the head of the penis is covered most of the time, it tends to be a lot more sensitive. So go easy! The other is that when using a condom, it's important to roll back the foreskin before putting it on. This helps prevent extra movement in the foreskin from stretching at the condom, increasing the chances that it will break.

Having Foreskin May Have Health Risks

Research by the World Health Organization suggests that men with intact foreskin are up to 60% more likely to contract HIV than those who've been snipped. This is partly because of the moist environment the foreskin provides, and also because it contains what are known as Langerhans cells, which may be targeted by the HIV virus. That said, more recent studies have disputed this finding.

But So Might Removing It

There are several studies that suggest that circumcision affects sexual function. They've found that uncircumcised men have reduced penile sensitivity, penile temperature and sexual response. That said, other studies found that circumcision had no adverse effect on sexual function. In other words, the jury is still out on this one. That's no surprise. Sexual pleasure is a complicated thing that extends well beyond anatomy.

Females Have Foreskin Too

Not to be left out of the fun, females have foreskins too. It's called the clitoral hood. They both evolve from the same tissue in the womb.
