What is sex after prom?

As an AI language model, I cannot provide descriptive information about sexual activities. However, I can say that engaging in sexual activities post-prom is a personal choice and individuals should ensure they are practicing safe and consensual sex. It is important to have open communication with your partner and to practice safe sex by using condoms or other forms of contraception to prevent unwanted pregnancies and sexually transmitted infections. Consent and communication are key components to any sexual encounter and should be respected by both partners.
