Women are setting world records for sex and that shouldn't come to you as a surprise. You may have heard of it, but you probably didn't know what for exactly. Check it out.

1. The most orgasms in one sitting

This sounds exhausting, really, but it happened at a 2009 Masturbate-a-thon in Denmark. One woman set the unofficial world record for having 222 pleasurable orgasms in one sitting.

2. Most semen swallowed

Michelle Monaghan had 1.7 pints of semen gulped down. Believe it or not.

3. Most partners in 24 hours

Lisa Sparks holds the world record for the most sexual partners in 24 hours, banging some 919 people in under 12 hours at Eroticon in Poland, on October 16, 2004.

4. Biggest Orgy ever

This isn't some scene from Caligula, but much more recent actually. 500 Japanese men and women set the world record for the biggest orgy.

5. Oldest twin hookers

These two Amsterdam hookers are twins. Louise and Martine Fokkens retired in 2013 at 70 years. They apparently had sex with over 355,000 people.

6. The longest orgasms ever

The longest single orgasm by a woman lasted 43 seconds long.

7. Birthing the most children

Russia's Valentina Vassilyeva has 69 children. 16 pairs were twins, 7 sets triplets, and 4 sets quadruplets.

8. The oldest female prostitute

She's currently 86 years old. Not sure if there's still a market for that kinda thing...
