How Do Boys Know They Are Not A Virgin Were There Also Women Castrated?

Were there also women castrated? - how do boys know they are not a virgin

She told me about this old story (cruel), a beautiful girl, the poor son of a wealthy landowner and he has insisted that the girl to break that led some doctors in Vienna and wants her ovaries. In this way they could have a relationship and not with their children and might even his marriage to a rich girl and have children with this. The wealthy family was murdered, and she alone ended. She joined is a kind of prostitution, but she only had sex with virgins men learn everything you need to know a woman (presumably because it is less likely to return if she can not protect against sexually transmitted diseases, because someone had sex, was still "safe").
I do not know how ths story is true, but I'm curious to know if back into the past, have also been cases of female castration, the less well known, not just men.
