100,000 men will soon "knock boots" with the sluttiest girl in Poland. A woman is planning to have sex with 100,000 men and hopes to set the record for the Guinness Book of World Records, for most sexual partners. Sounds more like she wants to set the record for lowest self esteem.

21-year-old Ania Lisewska of Warsaw, Poland says it's her goal to travel the world and have sex with at least 100,000 men. She wants it to last at least 20 minutes with each guy . . . and she's already knocked out 284 men.

Oh . . . and she has a SERIOUS BOYFRIEND. She says he was, quote, "not thrilled [but] had to come to terms with it."

But her goal of 20 minutes REALLY makes her plan far-fetched. At 20 minutes per session, it would take her three years and 10 months of nonstop sex . . . without taking a break or stopping to sleep . . . to get through 100,000 men.

If she only has sex on weekends, it would take her approximately 20 YEARS.

She even has a Facebook page.
