Can someone explain to me what has happened with the gusset inside womens underwear?

Serious post and Im losing my mind -- WHY does my gusset in all of my underwear sit so far back?

I wear appropriate sizing for my body! I feel insane, almost all pairs of my underwear, the gusset is at my taint or I even had one pair that pretty much went to my b-hole, which not only made me so angry but I was laughing so hard because of the absurdity of it.

Anyone else deal with this? Anyone have suggestions on GOOD underwear!?!?! The most normal pair I have worn are Pact but theyre already giving out in stretch and getting loose and diaper-y as I wear briefs. HELP.
