As a kid I remember watching this movie about this teenager who is cursed and every time he is horny he turns into a monster/creature. I believe there is a girl in the movie who also becomes cursed. It was either in the mid to late 80s that it was released. Does anyone know the name?:confused:

Maybe Michael J Fox' TEENWOLF?

I don't think I've seen it but it sounds similar to Idle Hands, the one about high school kid who's stoned all the time and his hand is possesed by satan and it's killing people, but he's to stoned to notice.

Sounds like My Demon Lover (1987) with Scott Valentine...
