The thin skin covering the vagina entrance is called a HYMEN. Girls with a hymen sometimes bleed when they first have sex. Girls with little/no hymen do not usually bleed the first time. Girls can lose the hymen by climbing trees and riding bikes. Some girls are even born without it. Girls with no hymen are still virgins, as long as they do not have sex. There is no way to know if someone is a virgin. Not every girl bleeds the first time she has sex. Keep your virginity and be proud-its cool!
