Once Bitten (1985)

The comedy horror film Once Bitten (1985) stars funnyman Jim Carrey as Mark Kendall, a naïve, horny high school student who wants to plow his girlfriend, Robin (Karen Kopins), but she’s not willing to put out. Enter Countess (Lauren Hutton), a four-centuries old vampire that needs to feast on the blood of virgin dudes in order to maintain her youthful looks and keep her immortality. Well, it looks like the blood-sucking babe is having difficulty finding male virgins, especially at the L.A.-based singles clubs she patrols. It is at the said club where Countess crosses paths with Mark and his buddies Jamie and Russ (Thomas Ballatore and Skip Lackey) as they're looking to get lucky and laid. While Mark’s hormones are ready to explode, he’s a soft touch for the vampire and her seductive ways. After a couple bites from Countess, Mark starts going through a vampirish transformation that can only be stopped by intercourse with Robin. This bawdy romp serves up plenty of laughs, along with full nudity from Skip Lackey, butt from Thomas Ballatore, and shirtless sweetness from Carrey in a penis-checking shower scene. Come for the comedy, stay for the flesh!
