Clear verbal communication without intimidation or threats = consensual sex.  Both parties must be awake when the act occurs; and, many states have laws that a person must be sober or not mentally impaired in any way in order to give true consent.  

To help you communicate your feelings clearly, both girls and boys, think about how you’d respond to social pressures about drinking, doing drugs, having sex or anything else that might be difficult for you.  Try to clarify what role sex plays in your life, what role you want it to play and how important is it to you to be “popular.” 

Talk with your friends (they’re probably just as confused as you are) or school counselors or even (yikes) your parents to help you sort things out.  Maybe role playing how to express your desires and limits under difficult circumstances will be helpful.  Maybe ask a teacher, student group or counseling center on campus to present a program about how both boys and girls could handle themselves on a date.  Find an e-book on this subject; there are a lot of good ones available.  This is an ongoing process, even for adults, but trust your instincts and know that the clearer you are, the easier it gets over time.    Crime Prevention 101
