Answers to objections
Will you get sweaty bollocks?
No, not with the wind whistling through your nethers.
Can you wear shoes?
Of course. Your feet are important, and should be protected.
Will you get grazes if you fall off?
Probably. Last time I fell off I was full clothed, and got grazed through the fabric. Best to stay on.
"I've got other naked activities I'd rather do first."
All naked activities are good, but don't feel obliged to do them in any particular order. If you get the chance to cycle naked, take it!
Finaly, congratulations to Jay Clocks for posting a picture. More please!
