Anyone use them? I switched over to them a year ago and I really prefer them over pads or tampons, but one of their advertised features is that you can wear them during your period for mess free sex being as they are essentially a diaphragm working in reverse. Do you think it is acceptable to use them during sex? The intended use is that of a tampon or divacup, but I suppose it could have contraceptive properties by preventing sperm to enter the uterus. The website says that they are not intended to be used as a contraceptive device, but then again so does my basal body thermometer. I can't remember if I had talked about this before on this board or on Catholic Answers.
