Three women were sitting in a coffee shop, talking about their sex lives.
The first said, "My husband is like a champion golfer. He has spent the last 10 years perfecting his stroke."
The second one said, "Mine is like a champion racing driver. Every time we get into bed, he performs several hundred exciting laps."
The third one, looking annoyed, said, "Mine is like an Olympic gold-medalist in the 400 meters."
"How so?" the others ask.
"He has his time down to under 45 seconds."
