Don't use this line on someone else, or you risk losing the person and feeling bad about yourself. Respect your partner's feelings and beliefs. Abstinence means choosing not to have sex, and it isn't an outdated idea. It's an important option to think about. A lot of young people like you make the choice to wait.
Some people abstain because of religious or spiritual beliefs or because of personal values.
Others abstain to avoid pregnancy or STDs, or just because they aren't ready to have sex. You should feel good about your choice. And if you have a friend or partner who abstains, give him or her your support.
