Women and men who dress in a sexy way, drink a lot, like to kiss, or enjoy someone's company have not already consented to sex. The difference can be rape. Any sexual activity must be mutually agreeable to both parties. Clear consent must be given before sexual activity begins. Alcohol inhibits clear thinking, makes talking and listening more difficult, makes it harder to assess risk, and can increase aggression.
Consensual sex requires sober, verbal communication without intimidation or threats.
Additionally, being drunk is never an excuse for raping someone. Do not take any beverages or open container drinks from someone you do not know well and trust. At a bar or club, accept drinks only from the bartender, waiter or waitress. Be alert to the behavior of friends. Anyone appearing disproportionately inebriated in relation to the amount of alcohol consumed may be in danger.
