Ceru, ka anglu valoda daudz maz ir saprotama.. tikko pati atradu linku http://menstrualcupinfo.wordpress.com/virgins-and-menstrual-cups/
Both menstrual cups and tampons can break the hymen, but it really depends what kind of hymen you have, and if you even have one at all! Some people were born without one. Others have already torn it with certain sports or other activities.
Again, some people are born without a hymen, or break/tear it by accident while doing normal, non-sexual activities. For example, the hymen can be torn or broken by horse back riding, riding a bike, dancing, bending and stretching, falling down too hard, gymnastics and other sports, self exploration, doctor exams, and using tampons.
