Nope! The vagina is a muscle that can stretch and accommodate all sorts of things, and then collapses back in on itself when it's empty. I have found that when I am using it a lot (inserting a cup every day, or having sexytimes a lot), it "loosens" but only because I'm training the muscle to relax and accommodate. Every month the first time I use the cup my vagina is very "tight" again because the muscle forgot how to open.

If anything, the cup could help strengthen your vagina since you'll be holding it in place with those muscles.

^^Exactly what I was going to say. The conscious ability to relax and contract your muscles on demand that you will learn with cup use has no significant negative effect on muscle tone. Think about this-- those that go through physiotherapy for incontinence or other reasons often use vaginal balls inserted to strengthen those muscles. In a way, the cup does the same thing.

I think this makes much sense what you both said. But I to have often wondered about the cups making me loose or rather it shows how tight you really are? As I can not wear my small Yuuki cup (my least favorite, way to firm) as it is the firmest cup I have but my pelvic floor just pushes out instead of pulling in but with my Keeper my 2nd firmest cup of the ones I own I have no problem.

No, this is a common but fundamentally wrong idea about how vaginas work. Childbirth tears the muscles which affects muscle tone; putting reasonable sized things in there doesn't.

In short: NO. For a more detailed explanation why you might want to have a read of this great Scarleteen article on tightness: http://www.scarleteen.com/article/advice/a_few_choice_words_about_tightness :)

Teacupcake89,
Thanks for sharing that was a good read. And makes even more sense I think we sometime do way too much thinking about loose and tight. I mainly worry about it because I don't want to develop incontinence as I age and one time I freaked out when my cup fell out so I went and bought vagina weights. LOL
