I bought myself a Mooncup UK about a year ago, and it worked fine the first period I tried it out. The second time, though, I got a Candida infection. I got a bit worried, because I had pretty bad chronic vestibulitis for several years when I was younger, but had been trouble-free for quite a number of years. Anyway, I managed to get rid of it with creams and suppositories, and boiled my Mooncup thoroughly before using it again, the next period (the third with the cup). Lo and woe, another Candida infection. After that I haven't dared use it again, but have gone back to my usual homemade cotton pads and occasionally a type of tampon we can buy here that contains lactobacteria (they work very well for me, but they are quite expensive). I've had no yeast infection since I stopped using the cup.
Anyway, I think the reason for the yeast infections wasn't really the Mooncup, but the fact that my mucous membranes are still pretty sensitive after that horrible period when I was younger (I'm pretty fair and I have sensitive skin in general). Insertion went pretty well; I managed to fold it well enough to insert it with no particular discomfort, but when I removed it I had more trouble. My fingers are pretty small and short, so I found it very hard to fold it up before removal. I had to pull it out best I could, and kept hurting myself. My theory is that when I removed the cup I got tiny (possibly microscopic) ruptures, and that the Candida got its toeholds there and got happy.
My question now is about the LadyCup. From what I've been reading, it appears to be softer than the Mooncup UK, and more squishy. So those of you who have tried both, and had trouble with removal of the Mooncup, do you find the LadyCup more trouble-free? I'm asking, because I'm thinking that a cup with a softer rim, surface and general texture might be more gentle on my tissues, which could be what would make me dare try again. I think the cup is a great invention, and I would really love it if I could make it work... Any thoughts on the matter are welcome!
(Apologies if any terms I've used seem strange, but English isn't my first language and my vocab might not be really up to par in this context... XD)
EDIT: Oh, and in case it matters, I'm 42, no kids, and so used the large Mooncup.
EDIT 2: What I want to know is if people find the LadyCup easier to remove than the Mooncup! I appreciate all tips for curing YIs, but my goal is to avoid YIs to begin with! ;)
