There is always a slight problem when you have sex with lots of different people. You are bound to run across the predators and psychos on a regular basis, probably more often than their regular occurrence in the general population. There was that weird Al Pacino movie 'Cruising' that showed what's what in the gay world. I imagine it would be banned now for being politically incorrect for not showing gays as being stable, heartwarming, married suburban heroes.

Just heard about this - "The Smiley Face Murder Theory"

I'd look for a gay/trans man, since among the major serial killers, almost half are gay or trannies.
