a guy who is paid to screw a woman. Basically, it's a male prostitute. Sells himself for money because he's a loser and can't get a girl friend so he tries to make himself feel good inside by screwing a girl. He tries so hard but still isn't happy so later in life he commits suicide by slitting his wrists an neck.
