Okay folks, I just had another try at using the diva cup I bought 1 1/2 years ago that I have never really used. That's it, I give up, I only have a few years of menstruating left and it just seems that menstrual cups are not meant for me even though I have used tampons in the past (more than 20 years ago though) and also a diaphragm (also a really long time ago). Has anybody tried selling a used diva cup or keeper? And also does anybody know if there is anywhere that takes donations of such items? Since I just don't seem to be able to use them, it would be great if somebody else could. thanks.
