Men have never been pros when it comes to the female body, and a new video by LOLPervs just proves that point. While the poor men in the world are still trying to figure out all the mysteries of the female form, this new “sexperiment” confused them further by presenting a few of them with the latest trend in period technology, and not telling them what it is. After giving four different guys a menstrual cup, they asked the men to identify what the product is, and what it’s used for.

Let’s just say, they came up with some pretty creative answers.

I’ll be honest, this was a little unfair; even I don’t fully understand all of the workings of the female cycle either. To clarify how this gadget works for all you boys (and perhaps girls) reading this, the menstrual cup is a small device made of either silicone or latex rubber which make it easier to stretch and bend. Instead of using a tampon or a pad, the menstrual cup is used to collect a woman’s flow rather than absorbing it. In order to insert it, you bend it in half, and put it in as you would a tampon, letting the pointed end stick out. When it is inside the vagina, it will conform to the shape of its walls, and form a seal so that blood does not get anywhere else but the cup. If it’s used correctly, you won’t feel it at all.

A lot of women have been using menstrual cups nowadays because they are reusable, making them more environmentally friendly and less expensive. The cup can also be warn for up to 12 hours, and taken out to be washed with soap and water. When you are done with your period, you can sterilize the cup by washing it in boiling water.

Unsurprisingly, the men from the video did not get anywhere near that answer. Instead, their responses ranged from everything to a turkey baster, something to clean your ears with, a device that helps women pee like men, and most interestingly, something to help a woman breastfeed.

To see the full extent of their hilarious responses, watch the video above.
