Be aware that use of force, pressure, or coercion is unacceptable and can lead to sexual assault charges. Don't take silence as consent. Don't have sex with anyone who is drunk or passed out. Intercourse with someone who is unable to give consent or is physically helpless is rape, as defined by state criminal statutes. Seek education on rape prevention.
Many acquaintance rapes involve alcohol or drugs.
Avoid drugs and excessive alcohol in a dating situation. Judgment should not be allowed to become impaired.
