But with the ubiquity of cellphone cameras, a lot of people find the thrill to be difficult to resist.
Boudoir photography is as old as the camera itself, and every American household has owned once since about the 1960's or 1970's. Cellphones have jack to do with it.
Your advice would certainly be effective, but isn't it akin to telling teenagers to abstain from sex in order to protect themselves from STIs and pregnancy?
Pretty much. Probably just as effective, too.
Unless you make yourself crazy ensuring that you never appear naked near anyone who might have a camera (and everyone has a camera these days), you can't really guarantee that this will work.
Well, you can do a lot if you would stop frequenting orgies and stripping to the buff in the middle of the public library...
Seriously, are there a lot of places where one would typically get naked around groups of other people? I can only think of 2 places where I strip down to my birthday suit, and both of them are in my own house.
