However, it’s possible to find your cervix, if you're so inclined to try. First, wash your hands. Then, Esguerra recommends getting into a position where you feel comfortable—maybe squatting or having a foot hiked up on the toilet seat—and gently insert your longest finger into the vagina and advance it until you feel something firm. “A lot of people will describe the feeling of their cervix as feeling like the tip of their nose,” says Esguerra. “It feels very different from a vaginal wall, which is soft and pliable. If a woman isn’t sure if she’s finding her cervix, I would do a systematic, 360-degree [motion]. Anything that’s firm, that’s probably your cervix.” Of all the cups we tested, MeLuna offers the most customization: It sells a standard cup in four sizes and a ”shorty” cup, for users with low cervixes, also in four sizes. It also lets you choose whether you want a stem, ring, or ball grip and offers standard or “sport” firmness in all cup sizes, with the “sport” being firmer for athletic users who ostensibly have stronger pelvic walls. It also comes in three colors—blue, purple, and untinted. The flat fit design also allows menstrual discs to be worn during period sex for an experience that’s completely mess-free.

If you’ve adjusted it and still have discomfort, you may need a different size cup,” Dr. Taylor says. Dr. Taylor adds, “A menstrual cup can hold a good amount, and there should be less leakage with a cup than a tampon, but you still need a good seal and the right placement. Panty liners are a good idea if you’re self-conscious [about leakage].”

Bear down for easier removal

Eco-friendly: A person can use around 11,000 single-use menstrual products in their lifetime. Using a reusable menstrual cup that lasts for several years significantly reduces menstrual cycle-related waste. Additionally, a 2021 study recommends using menstrual cups as an alternative to sanitary napkins to help reduce plastic waste.

The cup itself is a little shorter and wider than others, which most testers found comfortable. However, its ridged stem is longer than other cups, possibly because the Lunette is slightly more squat. This may make it useful for grabbing, but the majority of our testers found it irritating and had to trim it. Empty the contents of the disc into the toilet or down the shower drain. If you’re using Flex Disc or Flex Plant+ Disc, dispose of the used disc in the trash. If you’re using Flex Reusable Disc, rinse with cold water and then clean thoroughly with warm water and a mild soap or cleanser (like Flex Foaming Cleanser), then air dry and store in its pouch until next time. In other words, a menstrual disc should be comfortable for both you and your partner during period sex—and that includes sex of all kinds (from penetrative to oral). There is a chance that one of you may notice the rim, but there shouldn’t be any pain or irritation. How much you or your partner may feel the disc depends on your position, your anatomy, and your partner’s anatomy. Less leakage: When correctly inserted, menstrual cups produce an airtight seal that prevents leaks.Budget-friendly: While buying a menstrual cup may have a higher initial cost, a person can save more long term as they do not have to replace the cup frequently. Flex Disc, Flex Plant+ Disc, and Flex Reusable Disc all fall into the ‘menstrual disc’ category of period products: Like a cup, they collect (rather than absorb) your period blood, but they’re worn in a different part of the vagina: the vaginal fornix. The vaginal fornix is your vagina’s ‘rear wall’—it’s the widest part of the vaginal canal, just beneath your cervix.
