Most friendships, acquaintances, and dates never lead to violence, of course. But, sadly, sometimes it happens. When forced sex occurs between two people who already know each other, it is known as date rape or acquaintance rape.
Even if the two people know each other well, and even if they were intimate or had sex before, no one has the right to force a sexual act on another person against his or her will.
Alcohol is often involved in date rapes. Drinking can loosen inhibitions, dull common sense, and -for some people -0 allow aggressive tendencies to surface.
Drugs may also play a role. You may have heard about "date rape" drugs like rohypnol ("roofies"), gamma-hydroxybutyrate (GHB), and ketamine. Drugs like these can easily be mixed in drinks to make a person black out and forget things that happen. Both girls and guys who have been given these drugs report feeling paralyzed, having blurred vision, and lack of memory.
