I am curious...
Why is the original definition the "proper" definition? And who are you to say what the "real" definition of something is or is not, or that words cannot have several different meanings depending on the context?
Is a 7-year-old girl who was born without a hymen automatically not a virgin, then? Did a 12-year-old girl who broke her hymen riding a bike or climbing a tree lose her virginity to that bike or tree?
And what is the "proper" word for a man who has not had sex, then?
