It seems like you were hanging around a rough crowd of individuals as a young lady. I think that young women never really question the social situations they walk into until it's too late and something bad happens. In these tumultuous times, women across the country need to be certain that the characters they encounter are trustworthy and wholesome. The golden rule is to know your friends well before hanging out, otherwise your trust might be betrayed. I just don't want this happening again to you.
One other thing, the poster above me recommended to press charges, which can be a good thing. Don't let these people dictate what you do with your life. You have your legal rights. If you knew the names of the men who victimized you, then you have every right to stand up for yourself legally. It's never too late.
