I never had an airgasm in a hot air balloon. I did join the mile high club with Hubbie before we got married. We have reconfirmed it many times. I have also been the sex partner for many new members both male and female.
Note: Having sex in Denver or even on top of Mount Everest does not qualify for joining the mile high club. To qualify it must include two people having sexual intercourse a minimum of 5280 feet above the ground.
