Because they think the full-brief is granny panties. I agree with you! Why suffer needlessly? That is the same as pointy toed shoes? The question is why? There is nothing worse than bikini panty lines on women!
Not all women are created equal. While you are looking at the texture and quality of the fabric that you are wearing, not all women like this type of fabric. I once tried the polyester panties, only to find they were extremely uncomfortable, so actually the quality of the fabric is not as important as comfort.
Personally, as long as I'm not on my period...a g-string is more comfortable for me. I think it's all about personal choices. Plus, A LOT of clothes (pants in particular) are not built for full brief panties.
I love on your period. It's lovely to be at the verge to cry wearing full brief panties on your period. Which I love on your period, is that I love too see the waistband of your full brief panties and you see the waistband of my boxer briefs.
I think it's up the individual person, whether they find full-briefs comfortable or something like g-strings. Everyone is different, so it's not unreasonable to think that everyone's preferences are also different regarding their choice of undergarments.
I think to each its own. Wear whatever makes you feel sexy and most comfortable. I also feel wardrobe plays a big part in the types of under garments you should opt for,revealing panty lines are a fashion faux pas.Under garments works best when they fit properly also.
I want to thank all of you for taking the time to answer this question. I do understand the importance of personal choice, comfort, and health. I'm also ashamed to say that my preference for what women wear is unchanged. I realize this is selfish of me but I can't help it. I love the sight of a full-bodied woman wearing kind of retro-style panties of yester-year. There is something so desirable about a curvy, unskinny woman wearing these type of panties. Please remember, I am a man and in alot of ways I'm kind of a shallow person when it comes to my thoughts on women panties.
