Its NOT true that your vagina/penis disappears if you abstain for long. Your vagina/penis is going nowhere, even if you abstain for life! Abstinence is when someone decides not to have sex, maybe until marriage. Its the BEST way to avoid pregnancy, HIV/AIDS and Sexually Transmitted Infections (STIs). You do not need to practice sex. If it's your time to have it, you and your partner will discover what is best for you.
