Okay, so, here are the details: I'm 22, sexually active, no babies; I've regularly worn disposable pads rather than tampons; average flow; I have a high cervix (I've tried several times to reach it throughout my cycle and never have), and I'm not incredibly active so I'm not sure how strong my pelvic floor/muscles are.
I'm thinking that the model 1 Si-Bell (or the Natu cup, since I don't know of any differences between the two brands) could be good for me because although the cup itself is not very long, the cup plus the stem is pretty long. Also, I read here that some women have been able to take out the Si-Bell just by pulling on the stem, rather than having to grab the bottom of the cup. And since, having to grab the actual cup itself (which apparently you wouldn't need to do with the Si-Bell) is why women with a high cervix are advised to get a longer cup, maybe the short Si-bell cup (with it's helpful long stem) would still be preferable for women with a high cervix. ..?
Next, softness/squishiness of the Si-Bell cup. It seems that most women find the softer cups to be more comfortable, but generally they take more time to get to open. I don't mind having to take a little bit longer on my learning curve, as long as it's not always going to be a hassle.
Something else I've heard is that if you have strong pelvic muscles and a soft cup, the cup might not have room to open up all of the way or it might move out of place because your super strong muscles are crushing it. I'm not currently very athletic/active but I'd enjoy having the option. I think I'd prefer the comfort-ability of a soft cup, but not if I'd have to worry that the cup would cave in and not stay properly open and then leak. Does anyone have any advice on the Si-Bell cup and how it holds up in general or if you're active/have strong muscles. Some advice on the strength of the pelvic muscles in relation to soft cups in general, or how to tell if you have strong muscles, might also be helpful.
Short Story: My main concerns are, if the Si-Bell (or Natu) cup would work with a high cervix (meaning, can you easily reach and remove it) even though it's a smaller cup, if you can figure out how to insert and open it without always having to fuss with it, and if you can be active with it without it being squished by your muscles, moving out of place, and then leaking.
Thank you for reading all of this and offering advice if you have any. :D
