Underwear

I know, it's been awhile, but I'm getting older and my mind's slower than it used to be. Ok, not really. Honestly, I just haven't been inspired to vent. Until yesterday.
I was getting ready for work, and knowing it was going to be an exceptionally long day, I always put a bit of thought into comfort. Is what I'm putting on now going to be comfortable in 16 hours?
Amazingly, I spend at least as much time choosing what underwear I am wearing as I do my clothes!
I started with the panty drawer. I wisely chose my favorite pair of panties--they stay put without cutting into your flesh. I really don't think that's too much to ask. Growing up in a family of women (and actually being a woman), I feel knowledgeable enough on the subject of women's undergarments to speak about it. I think every woman I know has panties she prefers and panties she avoids. My question is this--why is it only women's panties that seem to crawl up the posterior end of the wearer? And why is it that you can buy a package of three pairs of panties and still prefer one over the other two?
Every woman I know has panties she saves for laundry day or "that time of the month." Other women save those rotten critters for when they go on vacation, so they can just throw them away at the end of the day.
I have been married for close to 30 years and never once have I ever heard my husband say, "Hey honey, can you do some laundry? All my good skivvies are in the wash." There may be particular style he prefers, such as tighty whiteys or boxers or boxer briefs, but certainly not favorite individual pairs of underwear.
I mean why is that? It seems to me a butt is a butt. I know for a fact my hubby doesn't have tape on the of his booty that holds his underwear down. Is it that women are so worried about what their panties look like that underwear makers have completely given up on comfort? Well, this old lady wants comfort over beauty. Frankly, very few people see my panties. If burlap was comfortable and stayed put, that would be fine with me. (Okay, maybe burlap in lovely colors and pretty pictures on it.)
