Since anything goes here, I would like to share a tip that isn't genuinely risque at all.
Occasionally, however prepared one might be, the need will arise to use a public loo for other than a pee.
Facilities being what they are we all know you can carry toilet wipes in your handbag for that pristine finish.
Beware, though, if your entre-deux-cheeks area is sensitive to detergents or alcohol, because you can irritate it and even go all red. This is likely if you suffer from any dry skin condition.
Solution: Carry a handbag-sized tube of a serious, hypoallergenic, neutral-as-possible, detergent-free moisturiser. I use DoubleBase.
For a perfect finish, squeeze ample amounts onto the paper for a perfect finsih without abrasion. Repeat as needed and smooth the area semi-dry to leave some moisturisation.
Much better than even moisturising wipes because you can lots of much-thicker moisturiser right where it's needed.

Also handy for moisturising your hands before opening plastic supermarket bags.
