Although cups have become more and more popular, people still have a lot of questions about them! Here, we’re taking on the most asked questions about menstrual cups in general and the FUN CUP in particular.


Got a question we haven’t answered? You can ask it here.

Will I spill blood on myself?

To be completely transparent, you probably will get a little blood on your fingers sometimes. As long as you insert and remove your cup on the toilet or in the shower, though, you’ll be fine. Just don’t wear your white lace gloves while you do it.

How long can I leave it in?

That depends on your flow. Luckily, the FUN CUP holds 4-6x as much blood as a tampon, so your heavier days just got easier.
We do recommend that you clean it thoroughly at least once or twice a day.

Is it gross?

We don’t think so. Or at least it’s not more gross than any other kind of period protection. It does involve getting pretty familiar with your vagina and emptying blood from your cup between uses, so use your best judgment about whether you’re comfortable with that.

I have a heavy flow. Can I use the FUN CUP?

Absolutely! SIZE A holds four times as much as a regular tampon, while SIZE B holds six times as much.


I couldn't get it in the first time I tried it. What's wrong?

Any menstrual cup comes with a learning curve, but we think it’s worth it. The first time you try it, give yourself time to get a feel for how it fits in your body. If you find yourself tensing your muscles, take a few deep breaths and try to relax, or even walk away and come back to it later.


One quick thing to check is that it’s covering your cervix. If you’re experiencing a lot of leaking, your cup might be crumpled or sitting on one side of your cervix instead of under it.


We recommend using a backup method for the first couple of cycles, until you feel secure that you’re inserting the FUN CUP correctly every time.

What If I need to use the bathroom while I'm wearing it?

The FUN CUP is made with soft, flexible silicone that doesn’t interfere with your body’s normal functions. Some people find that their cup gets dislodged during a bowel movement, however. If this happens, just push it back when you’re done, bear down, and twist to create a new seal.

What if I need to empty my cup in a public restroom?

No need to worry about washing it in a public sink. Just wipe it out with a little toilet paper before you put it back in.

What if I drop it in the toilet?

Fishing anything out of the toilet is the opposite of fun, but at least it’s not your phone, right? If the worst happens, you can wash it off and then boil it for three minutes to sterilize it before the next time you use it. Besides, the lightly textured surface near the tip makes easy to hang on to.

What if I lose it? I don't want to waste my money!

We recommend keeping a cup at home in your bag, so you always know where to find it when you need it. Plus, if you buy two cups, you’re covered even if you do lose one. Worst case scenario, buying two FUN CUP kits is still cheaper than the $100 (80 €) per year you’d spend on tampons.

Which cup should I choose?

Let’s take a look at your options! Remember that these are general suggestions, and there are many exceptions to all of them. You know your body better than we do.


We offer the FUN CUP in two sizes: a smaller size and a larger size:


  • SIZE A – Smaller (2.1 in, Ø 1.56 in, 0.68 oz / 5,3 cm; Ø 4 cm; 20 ml)
    We made SIZE A with firmer silicone to make it easy to place and adjust a smaller cup. Good for: lighter flow, people with shorter vaginal canals
  • SIZE B – Larger (2.29 in, Ø 1.7 in, 1.01 oz / 5,8 cm; Ø 4,3 cm; 30 ml)
    The softer silicone holds your heavy flow without any uncomfortable pressure. Good for: heavy flow, people with longer vaginal canals


When in doubt, start with the EXPLORE KIT.

    Good for: people  who don’t know their size or want different options for lighter and heavier days. If you’ve never used a cup, start here!

What material is the FUN CUP made of?

The FUN CUP is made from medical grade silicone, a hypoallergenic, non-porous material that won’t trap bacteria over time. You can even sterilize it by boiling. Plus, it’s made in Germany, where sexual health products are regulated to ensure that they comply with EU standards for safety and health.

Where can I buy the FUN CUP?

You can purchase the fun cup here.

Can I use a FUN CUP if I'm a virgin?

The sexuality educators behind the FUN CUP believe strongly that inserting something into your vagina does not mean that you’ve had sex. If you’re concerned about your hymen, please speak to your doctor.

Can I use a FUN CUP if I have an IUD?

Be sure to speak with your doctor about any medical question. If you choose to use a FUN CUP with your IUD, make sure that you don’t pull the strings when you pinch your FUN CUP to remove it. To avoid this, you may want to ask your doctor to trim your strings short.

Can I use the FUN CUP if I have a tilted uterus?

This is another great question for your doctor. Not all tilted uteruses are alike, so the FUN CUP may or may not be a good option for you, depending on the angle.

Can I use it if I get bad cramps?

Yes. A FUN CUP won’t make your cramps worse. For some customers, using a cup even lessens their cramping.

Should I be concerned about TSS?

TSS is very rare, both in general and with menstrual product use. It is very dangerous and can also be deadly under some circumstances without treatment. TSS can occur for any one of several reasons and is caused by toxic strains of bacteria entering the bloodstream.


Symptoms of TSS:

  • sudden fever
  • shivering attack
  • sickness
  • vomiting
  • muscular pain
  • drop in blood pressure
  • dizziness


If symptoms appear, take the FUN CUP out and go to the doctor. Make sure to tell the doctor that you used an insertable menstrual product. If you have had TSS before, it is not recommended that you use the FUN CUP. To reduce risk of TSS please follow instructions for use. In general, we recommend consulting with your doctor before using a new menstrual product.

Can I play sports while wearing a FUN CUP?

Yes! The cup won’t stop you from doing any physical activity you like, from running to gymnastics.

Can I go swimming with the FUN CUP in?

Go for it! The leak-preventing seal works just as well in water.
