I feel absolutely disgusted. I'm getting down voted for saying it's wrong for an adult to masturbate in a school. I don't care why she did it, she should have done it at home. Stop trying to defend the actions of someone who got aroused at the idea of masturbating in a room meant for children.

Edit: Even more down votes. Masturbating in a school is the actions of a pedophile. A man masturbating in a school is a pedophile. A woman masturbating in a school is a pedophile. It doesn't matter why she masturbated in a school, it's still the actions of a pedophile. Stop trying to defend her.
