Speed of light sex! If you were to strip naked
Post# of 123723
If you were to strip naked and run around in a circle at the speed of 298 km/sec (the speed of light) it would theoretically be possible for you to screw yourself.
However, since you are not physically capable of achieving that speed at your age, you can easily accomplish the same result by Voting Democrat in the Nov. 8, 2020 election.
