Second, have a talk with your wife or girlfriend of even your mother about the art of sitting and standing while wearing a skirt. Women learn this at a very early age, but an inexperienced male can easily and unknowingly create visual havoc on those around him. Third, learn to sit with your legs close together at all times. This is an imperative, and for best results, should be practiced at home in front of a mirror before going out in public.
Why does this always get promoted as the correct way for a man to sit in a kilt!? It shows a complete incomprehension of why kilts are suited to men. It shows that the speaker is just as ignorant in their thinking that a kilt = womens skirt.

A man should be aware of not exposing himself but to sit with legs together is not anatomically reasonable. Of all the ridiculous statements I've heard come from anyones mouth about a kilt, this ranks as #2.
