I heard that if you you go horse riding you break the bit I your vagina that usually breaks when you have sex. Is this true?

Do you mean, rupturing your hymen? You probably do mean that. Yes, that can happen horseback riding, but very rarely.

Tick

Even if it does... you would still be a virgin.

My health teacher said that people used to say that a broken hymen meat that you were not a virgin until it was found that it could break other timess. Horse backriding was the same example she used!

You lose your virginity only when a penis enters your vagina.
