Choosing the right Soma Flex size depends on your body's needs and comfort. This guide explains the key differences and gives simple rules to help you decide.
Quick Answer
Start with the Soma Flex Vaginal Sizing Set to find your size, then choose the Soma Flex 40 or 55 based on which one you can wear comfortably for up to 16 hours a day.
Why Size Matters for Pelvic Floor Training
Soma Flex dilators work by gently toning your vaginal tissues through everyday movement. The right size is the one that feels comfortable when worn internally for long periods. If it's too small, you might not get the toning effect; too large, and you won't want to wear it consistently.
Both Soma Flex 40 and 55 are designed for longer wear, but they differ in size. Choosing the right one is about your body's unique needs and comfort, not about picking the 'best' size.
The Trade-Off Between Size and Comfort
A larger size may provide more tissue engagement, but if it causes discomfort, you won't wear it as long. A smaller size might be easier to insert and wear, but it may not offer the same level of toning for everyone.
The key is to find a size that you can wear consistently for up to 16 hours a day. That consistency is what makes the training effective.
Decision Rules for Choosing Your Soma Flex Size
- Start with the Sizing Set: If you're new to Soma Flex, begin with the Soma Flex Vaginal Sizing Set. It helps you determine which size fits your body best before committing to a single size. Do not skip the sizing set if you're unsure.
- Comfort is King: Choose the size that you can wear comfortably for up to 16 hours a day. If you feel any discomfort, size down. Consistency beats a larger size.
- Consider Your Experience: If you're new to dilators, the Soma Flex 40 may be easier to start with. If you've used dilators before and need a larger size, the Soma Flex 55 could be a better fit. Your experience level matters.
Soma Flex Sizes at a Glance
- Soma Flex 40: The Soma Flex 40 is one of the Soma Flex sizes for longer wear, selected based on your body's needs. If you're new to dilators or prefer a smaller size, the 40 might be a more comfortable starting point for daily wear.
Soma Flex 40 - Soma Flex 55: The Soma Flex 55 is another Soma Flex size for longer wear, chosen according to your body's needs. If you need a larger size for a more noticeable toning effect, the 55 could be the right choice, provided it stays comfortable for hours.
