I don’t know about everyone else, but I don’t normally factor in a person’s age when I help them find a cup. The only time that I would think about age is for younger users (9-14) and that’s based on my tiny framed niece. I bought her two cups when she was 9, and then another when she was 12. All size small because she hadn’t had any type of penetration (including tampons). However, I have heard from many users who prefer and are successful with a large cup even if they never had penis/vagina penetration.
The key is to find a cup that is comfortable and easy to reach. One of the best ways to narrow down a cup or cups would be to locate and get an approximate measurement of the cervix.
This involves inserting the middle finger, locating the cervix, and taking note of how far your finger was inserted before you reach it. Think of your knuckles as a guide.
If the finger could only be inserted to the first knuckle closest to the fingertip, you’ll most likely feel more comfortable with a cup that is labeled for a “low cervix”. A menstrual DISC might also be an option.
If the finger could be inserted to the second knuckle, almost any (not all) small-sized cups and most average-sized large cups should feel comfortable (in length) and should still be easy to reach.
If the finger can be inserted completely to the knuckle (top of a fist), a large cup would be the easiest to reach when it needs to be removed. Some cups are longer than the ‘average’ large, as well as cups labeled for a high cervix. A long stem might able help.
How to Locate & Measure your Cervix
If you have a low cervix and get a cup that is too long, it likely won’t be comfortable and may not even be able to be inserted completely. But that scenario isn’t as bad is getting a small/short cup and finding out that you have a high cervix. In this case, the small/short cup will migrate up (in) further near your cervix and may be difficult to reach and remove. This often sends new users into a panic.
If you would rather not go through the process of measuring your cervix, I would suggest finding a brand that offers two sizes for a low cost.
Next, if you have a heavy flow the large will have a higher capacity to allow you more time before needing to be emptied. You can also use a larger size even if you only have a light flow to ensure that you only need to empty the cup every 12 hours (or twice a day).
If you’re worried about the diameter, most cups (even large sizes) are folded down to the insertion point about the same size as a tampon or a thumb. However, some cups are more narrow than others and you might be more comfortable starting with one of those. Water-based lubricants are also very helpful.
To me, age, pregnancies, and penetrative sex don’t usually make a difference when choosing a cup. The factors that I use to help narrow down what might work for a user are:
cervical height – sizing for length
bladder/bowel sensitivity – how soft or firm
physical activity – how soft or firm
flow – sizing for capacity
I hope this helps.
Good Luck & Good Health <3
