Maybe because it's outside their bodies rather than tucked away, but men seem to have no problem getting it out - whether it's performing The Windmill on a drunken night out, hanging out in the locker room or sending photos of it to women online.
Women, on the other hand, have had a long history of battling insecurities about our bodies, and more crucially, being reluctant to talk about it. Now, a new ground-breaking site aims to improve the relationship we have with our reproductive organs.
The Beautiful Cervix Project invites women to submit pictures of their cervix online, in an effort to create more awareness around fertility.
The website, which is a grassroots movement, states: "The Beautiful Cervix Project encourages women to learn cervical self-exam and fertility awareness as a revolutionary path of promoting respect, confidence, and health. We believe that this form of self-empowerment and education will help contradict shame and misinformation around women’s reproductive health and choices, affecting positive change from the personal to global levels."
On the website, you can also buy a self-exam kit for $19.95, which includes a reusable plastic speculum, blue or magenta hand mirror, a 'Love Thy Cervix' flashlight, self-exam instruction sheet and water soluble lubricating jelly packet.
HuffPost US quoted Kat Stoeffel at New York Magazine as saying: "It's too bad this self-love movement requires employing a speculum, a flashlight, and one real chill friend" -- photographing your own cervix isn't exactly easy. But the effort is definitely appreciated by the site's users. Commenter Allie posted: "I really really appreciate these photos, it’s been a great learning experience for me."
We're not quite sure HuffPost UK Lifestyle is ready to grasp the Love Thy Cervix flashlight just yet - the pictures on the site are fairly graphic.
With regards to fertility however, checking your cervix for signs of ovulation can help if you're trying to have a baby.
Toni Weschler, fertility educator at Babycenter.com says: "As you approach ovulation, your cervix will become soft, high, open, and wet — you can remember this with the acronym SHOW. After ovulation, these signs reverse and the cervix becomes firm, low, closed, and dry.
"The best way to learn about your cervix is to start checking it once your cervical fluid becomes wet and continue checking for a few days after your temperature has risen. That phase of about five days is when you'll notice the most abrupt change."
