It’s all fun and games — until someone drops dead.

Sex is great, no real need to state the obvious. But like everything else pleasurable in this world, it can kill you. It can kill you until you're really dead. For these poor souls, sex was the end-all to the big game. Not entirely the worst way to go out, however …

Orgy Overstimulation

Sergey Tuganov was your typical Russian teenager in search of a coveted threesome. When the time finally came, two women bet him $4,300 he couldn’t please them for 12 straight hours. Like any thick-skulled male, Tuganov took the bet and popped Viagra to enhance his performance. Unfortunately, following the 12-hour romp — and before he got be paid — Tuganov dropped dead from a heart attack. Moral of the story: don’t take a bet you can’t collect on.

Sparks Fly

Pain is the name of the game, unless that pain results in the death of your sexual partner. Kristen Taylor, 27, learned this lesson the hard way when she was electrocuted to death by a pair of nipple clamps during foreplay. Her husband originally told police she died when she was shocked by the hair dryer, but eventually came clean and confessed to the accidental electrocution by nipple clamps. Everything in moderation, it would seem, including nipple clamps.

Italian Stallion

Kenneth Pinyan wasn’t your typical Boeing engineer. Everyday after work, Pinyan would drive to a farm outside of Seattle and indulge in some one-on-one time with the horses. Sadly, on one particular occasion, a stallion must have become too randy and went “too deep,” rupturing Kenneth’s colon and sending him to the hospital where he died as a result of his injuries. The outcome led to a Washington State law making bestiality a felony punishable with up to five years in prison. Damn you, Kenneth.
