How to use Flex Disc during period sex

1. Use an empty or recently emptied menstrual disc

Having sex with a full menstrual disc isn’t risky, but it may not be super comfortable. Using a fresh or less-full Flex Disc (i.e. it’s only been in for a few hours and/or you’ve just emptied it out by bearing down while on the toilet) is a better move since that way, you won’t have to worry about leaks caused by pressure.

Wondering how to insert your menstrual disc securely? Here’s a quick tutorial:

2. Use it WITH birth control

While it might (sort of) resemble a diaphragm, Flex is not a contraceptive. Use it in conjunction with your normal birth control—even if it’s a type that goes inside your vagina, like an IUD or contraceptive ring. And yes, you CAN get pregnant on your period if you don’t use a form of birth control!

Quick notes about things that can be worn with the Flex Disc:

  • Condoms: Totally safe to use these with Flex.
  • IUDs: Using a menstrual disc with an IUD is certainly possible, but if you have an IUD, we always recommend chatting with your OB/GYN or healthcare provider beforehand: They’ll have a better idea of how your IUD is placed and where your IUD strings hang in relation to your unique anatomy.
  • NuvaRing: The Flex Disc is safe to wear in conjunction with NuvaRing. Just be sure to prioritize your birth control by inserting it first and then following up with the disc. We also recommend giving your disc a quick check upon removal to be sure you don’t accidentally remove your Nuvaring.

3. Get wet

To start things off on the sexiest note, we recommend doing some foreplay, tantalizing talk, or anything you like to get you excited and naturally lubricated—including oral sex. You heard it here first: Flex Disc users experience no period smell and leakage is rare, especially if you insert a fresh disc before jumping into bed (or couch… or kitchen counter…). So, go ahead and enjoy sans-worries.

P.S. Only water-based lubes are considered safe for use with the Flex Disc.

4. Get in position

The best sex positions when using a menstrual disc are missionary and doggy style. If you’re having sex in one of these positions, it’s very unlikely your partner will feel a menstrual disc.

5. Rearrange all you want

If you switch positions and your Flex Disc shifts, don’t fret. It rarely happens—but if it does, use a clean finger to tuck it back in behind the pubic bone. Sometimes, even a couple of Kegels are enough to get your disc back into place.

6. More ohs & oh yeahs

Some people experience stronger orgasms when wearing the Flex Disc because it gently rubs against the cervix during intercourse. Another fun fact? Stronger orgasms might even make your period end sooner. Yes, we DO take thank you notes!

7. Throw in a vibrator

Period sex doesn’t have to be partnered sex. Nor does it have to be body parts-only. Break out your nightstand stash and put your go-to vibrator or dildo to work—either externally or internally. In the market for some new toys? Check out our favorite vibrators of 2021 here.

8. Immediate removal can be tricky, but don’t panic

Removing the Flex Disc after sex can be harder than putting it in for a few reasons: Your vagina gets longer and your cervix moves higher up in your body when you’re aroused—plus, vigorous movement (*ahem, penetration*) can shift your Flex Disc further back.

Remember: There is literally no way your Flex Disc can get lost in your body. You’ll ALWAYS be able to get it out, we promise! After sex, just wait about 30 minutes to an hour for your vagina to return to its normal state before you try to remove your disc.

Then, push or bear down with your pelvic floor muscles (as if you were trying to poop). Do this while you have one finger inserted, so you can hook your finger under the disc when you feel the rim move forward down your vaginal canal. For even easier access, try removing your disc in the shower while in a squatting position. The warm water will keep your muscles relaxed and your cervix will be easier to reach. 😉
