Why does Purity Culture within Christianity get so much hate?

Waiting for marriage is a great thing. There's nothing toxic about it. As a man, it's my duty to gift my virginity to my future wife. If I don't get married I'll die pure. So be it. I'd even say sex only gains meaning and beauty when shared between a loving and married husband and wife. Can someone explain how anyone could hate that?

Edit: Wow, really didn't realize how ignorant even some Christians can be. None of you actually know what purity culture is. And the amount of people saying that it's okay not to wait is concerning.
