Today, science informs us that some girls are born without a hymen, that it can be so stretchy as to not break, even during penetrative sex or fragile enough that it breaks during regular exercise.
The hymen has relatively few blood vessels and so bleeding is not guaranteed, even if it is broken during sexual intercourse.
Just like so many other parts of our anatomy, the hymen comes in many shapes and sizes. Every girl is different. This means that whilst using a sanitary product that is inserted like a tampon or Butterfly Cup may disturb the hymen, it also may have no effect whatsoever.
Therefore a woman should choose the right sanitary product for her based on health, value for money, the environment, convenience and peace of mind.
