What should i do, my roommates are trying to blackmail me into being a slutty sissy?

Don't be a pushover. Stand up for yourself. Tell someone. Those s l u t s are trying to scare you into their doing...if you let them, they'll continue to be s l u t s towards you, no matter what. Tell them to back off and leave you alone. If they send it out, let them. After all, it's their stupid, undignified word against your truthful word. Would your mum believe you or those two cheating scum? And if they blackmail even more, and nothing works, take off everything and tell them to stop being retards. You can't just turn gay and stupid just for those two unworthy pieces of crap. Stand. Up. For. Yourself. No matter what. If it gets down and dirty, contact the police. Sure, it's dobbing them in, but this proves you are NOT scared by them. Hope you prevail against the s l u t s.
