1. Never take naked pic or film your love making.
(You'll never know when your hp/ digicam/ computer needs servicing or if your disc will be misplaced)
2. Never keep naked pic of your ex gf/ bf. Destroy them when you move along.
(Their current squeeze might not like it if it's leaked out)
3. Always keep your pubic neat and tidy.
(You'll never know if the whole world will gets to see it someday)
4. Always wear a nice bra with matching thongs.
(Reason ditto above)
