I'm 27 with no kids. I don't plan on having kids and it seems like my vag has a death grip on this damn thing, lol. The only direction it moves is up.
I'm thinking of getting a Divacup. They're about the same length. I think the only real difference is that the Divacup has a longer cup and less stem.
The website says it's only 1/8 inch difference between the 2 sizes. Does it really make that much of a difference? I just don't get how such a small size difference makes any difference at all but then again i don't have children, lol.
