Before we cap off this year's day of love, affection and all that other mushy stuff, I think it's time to discuss something that plagues a horror movie buff like me. And that is the fact that sex isn't safe on any level in these flicks. As tempting as it is for featured characters, we all know it's very costly majority of the time. Whether it's Michael with some awkward timing or Leprechaun exiting out of a space marine's favorite appendage, these mentioned serial killers sure know how to keep a couple from getting off. Enjoy, y'all.
