Merlin, Al Bundy stars in a soap "married with children". so depending on what the English programming offers, you may have been able to see it. It is very hilarious, and of course shows life with a spot of humor, just in the same way as "The simpsons". My opinion.
I would also state, that we should watch how women sit. Without staring.
As long as any unwanted vieuws are prevented, we are men, and should be able to sit RESPECTFULLY, but slightly wide legged, although I do think, besides very manly outfits, kilts, that sitting legs crossed or neatly together is good ettiket, is a fine way to sit with a skirt on. Wearing skirts can or may require some refinement and extra attention to our manners. I find ( having to be ) that being more refined is an extra plus point with wearing skirts. It is so easy to be a rough and go man, it takes some work on our part to be somewhat refined in our ways, but is very rewarding.
As for adjusting our .... well, actuall that is a very natural occurance, and I think that if doen with tact, and "neatly" should become something which is accepted as being a needed thing to be done, and in public. But if at all possible, any handling of any genetal area should be done in private. Thus not making any suggestion whichever way to others. Just as women will from time to time adjust their breasts if they do not sit quite right in their bras. In an Ideal situation there is always a apart place to do those things, but if you are on the street, ( no where to go to private,) then a (needed

) quick adjustment is the only thing left to do. It is not only the shortcommings of pants, but also of any constricting underwear, which the classical true kilt wearer has no problem with at all.
As most of us do wear underpants, of some form, there is always a moment that requires some adjustment, and hope that it is when a private lokation is available. But I for one wil not and Cannot go on walking, whatever if my things are somehow unpleasantly placed or even clamped uncomfortly.
it is all about how we normally act, behave, not what we do in "emergency situations". other people should also react appropriately, giving men the chance to do a very needed adjust in public, as long as it is just that.
A man is the same man in a pair of pants or a skirt. It is only the way people look at him that makes the difference.
