Many couples refrain from sexual intercourse during "the period" simply because it's too messy. The Flex Company aims to provide an alternative to conventional pads and tampons, which can block blood and can be worn during intercourse.

Dubbed Flex, the sleek and disc-shaped menstrual blood blocker can be worn for up to 12 hours and it comes in just a small packet.

"Flex is a revolutionary device that is changing the way women think about their menstruation," said Dr. Jane van Dis, an OB-GYN.

"Unlike other feminine hygiene products, Flex conforms to any woman's body making it the most comfortable product on the market. It's safe, easy to use, BPA-free, and hypoallergenic, and is not associated with TSS," she added.

Flex is a device that temporarily blocks the passage of menstrual blood by creating a soft barrier to the cervix. It's barely detectable by partners and can be disposed every after use.

"Flex is so shockingly comfortable that women tell us they forget they're on their period while they're wearing it," said company CEO Lauren Schulte.

The company said its mission is to help couples become more intimate even during periods. The lack of education drives a lot of stigma about women's periods, however, making them feel more comfortable during this time by better products could create a positive change.

"If we can begin educating men and adolescent boys about female anatomy and menstruation in a positive light, knowledge will help shift our ideas - not only about menstruation - but about women," the company said.

On the company's site, the tampon alternative will be out in the market by fall of 2016. The company, however, said they are open for preorders in April to be shipped by September. About 20,000 women have already signed up for a free trial of Flex, but the definite price of each packet is yet to be released to the public soon.

The San Franciso-based company was funded by Amplify.LA.
