A Russian man died after swallowing a bottle of Viagra to keep him going for a 12-hour sex marathon with two female friends.
The women reportedly bet Russian mechanic Sergey Tuganov $4,300 that he wouldn't be able to follow through on his half-day sex marathon claims. But soon after winning the bet, the 28-year-old died of an apparent heart attack.
One of the women, who identified herself only as Alina, said, "We called emergency services but it was too late, there was nothing they could do."
