I don’t remember much, I watched this movie a couple times as a kid in the 90s on pirated VHS so my memory is shaky. I remember it may have been a sex comedy of some sort. Drugs may have been involved, a stable, a horse? Maybe the drugs made it seem like a woman had a horse’s head. That’s all i really remember and the stupid movie has been pestering my brain for weeks now!HELP!
Maybe “Equus” (1977)? Or there might be another version, but the sex and the horse sounds like Equus.
