Phelps Earns Another Gold Medal

Well, it sure sounds like Michael Phelps has endurance outside the pool, and no, not while sucking down bong hits.

Michael Phelps deserves another gold medal -- for stamina in the sack, according to a stripper who claims she had a threesome with the swim champ.

"The sex lasted for about three hours," Baltimore stripper Theresa White told Britain's News of the World. "Michael should get another Olympic gold for marathon love-making!"

White, 25, claims Phelps invited her and some of her lap-dancing pals to his apartment, and that's where the action allegedly took a kinky turn after two hours of drinking. White said she approached Phelps for a three-way: "He told me he'd never had one before but said it would be with me and then pointed at another girl.
