I can't believe I stumbled across this one. I remember reading this book in the 80s. It was absolutely awful. A teenage boy develops telekinetic powers (I don't remember if it was ever explained how he got them) and they manifest whenever he's horny. So it's your typical nerd-gains-powers-and-goes-on-a-vengeful-rampage sort of story, except in this case, the rampage involves long-distance psychic rape, and I also vaguely recall a scene where the kid is making out with a woman, finds out "she" is a transsexual, and smashes her against a wall or something. Yeah, real classy. It was like the id of schlocky 80s horror films spewed on pulp.
