Based on several posts made in another thread I did some research. Here are my findings.

What is dating violence?
Dating violence is any intentional sexual, physical or psychological attack on one partner by the other in a dating relationship. This definition reflects the belief that all forms of abuse are harmful and worth taking seriously. A wide range of harmful acts can occur in dating relationships that go beyond what people traditionally think of as "serious" abuse, that is, physical or sexual violence. Although both men and women may act abusively, the abuse of women by men is more pervasive and usually more severe.
Dating violence is more likely to happen when the aggressor has been drinking. This often leads people to blame alcohol for the problem. In fact, abusers themselves use alcohol as an excuse for being violent.
Sexual abuse includes unwanted sexual touching, using force or pressure to get a partner to consent to sexual activity, rape and attempted rape, and attempting or having intercourse with a person who is under the influence of alcohol or drugs. These kinds of abuse are more often directed at women. While all these acts are damaging emotionally, they vary in the extent to which they result in physical injury
