Alcohol is a drink that adults can have but it's only for grown-ups because it can make them feel dizzy or get drunk. When people have too much alcohol, they might not make good decisions or might not be able to remember what they did.
Sex is when two grown-ups who really like each other decide to do special things together, like hugging, kissing, or touching each other in private parts.
When people drink too much alcohol, they might not make good decisions about who they have sex with or whether they really want to have sex. Sometimes people might not be able to remember if they had sex at all because they drank too much.
It's important to remember that you should always say no if you're not sure about having sex or if you've had too much alcohol. Drinking alcohol and having sex is something that grown-ups can do responsibly and safely, but it's important to be smart and think carefully about the choices you make.
