Sexual behavior inside a prison is both forced and encouraged by prison subgroups. Homosexuality in prison depends to a large extent on the innocence of young prisoners who are experiencing prison life for the first time. Often, older prisoners looking for same-sex relationships can sometimes grovel by offering several things such as food, money, drugs, protection or cigarettes. At some point in the future, these “loans” demanding sexual favors in exchange for reward will be called out. There is a prison code which requires repayment of favors; the inmate who tries to resist will find himself or may very quickly find himself face to face with the brutal force of prison society. Prison rape usually involves physical assault, which according to PREA (2003), the attackers themselves have suffered much damage to their masculinity in the past and most do not consider themselves homosexual. Victims of sexual assault sometimes become violent, aggressive and may even kill the person who raped them. Human Rights Watch (HRT) researchers found that prisoners "who fit part of the following description" are more than likely to be victims of rape: physically weak, young, short, first-time offenders, gay, white, unassertive, intellectual, shy, unaggressive, unintelligent, possessing “feminine” characteristics such as long hair or a high-pitched voice, or “passive”; or have been convicted of a sexual offense against a minor. Researchers also found that inmates with multiple overlapping characteristics are highly likely to be targets of abuse more than other inmates. The report concluded that in order to reduce prison rapes, prison authorities should be much more careful about grouping inmates together and, in general, avoid victims rarely being able to bring an individual action for personal injury against the attacker. The problem with these lawsuits is the difficulty in finding lawyers willing to defend these cases against other defendants who are likely trial-proof. The victim often relies on correctional officers to monitor the incidence of assault and intervene when an assault is in progress or about to occur. Sexual assaults of this nature rarely take place in full view of the police to prevent them from being able to intervene. This confidence rests on two other critical assumptions that are not necessarily true; the guard wants to intervene to prevent the attack and he is not himself the perpetrator. Researchers have often noted that instead of viewing prison rape as a crime requiring intervention, prison staff sometimes view rape as a way to deter other forms of prison violence. Second statement, corrections officers can offer the victim the best protection, assuming the officer is not the perpetrator of the offense.
