How do I know if consent has been given?

Consent is an agreement two partners aboutt he kind of sex or sexual contact they want to have. Consent means a clear, enthusiastic, and sober “yes”. Only a \"yes\" means \"yes.\" It can be withdrawn at any time, given for one kind of sex and not another, and must be given at every step of sexual activity. Remember, if you don't have someone's consent, you run the risk of sexually assaulting them.
