&gt;If it’s reversed and a woman asked if she had to throw out all her comfy granny panties because the guy she’s with says wear bikini or thong underwear, yeah, I get it

Wait, why is that? Wouldn't the same logic as OC apply here - that it's not an obligation, but it's nice to show you are making an effort?

Not picking a fight, just confused.

There's the added complication that vulvas/vaginas can be easily upset by the wrong underwear (chafing, yeast infections, UTIs, etc). For some women, their choice of underwear is dictated by their health, not their fashion sense.

Going from full-on granny to bikini isn't necessarily an issue, as long as the fabric can stay the same, but going from cotton grannies to lacy thongs may not be possible. That might have to be a meet-in-the-middle scenario.
