It’s a combo of the pants being a poor fit, the pants being badly designed, and the pants being cheaply made.
Fashion industry standard drafts a single pattern for each style of pants in size 2/4/6, depending on brand, then just size it up or down without redrafting it to account for body fat distribution being uneven. So even if it’s the “correct” size, it may not actually fit your measurements. Cheap fabric tends to have less structure, and it won’t hold your body fat in as well as a fabric with a tighter weave.
You can get underwear with some padding that doesn’t squeeze around the seams if you want to avoid it.
I personally find thigh chafing to be more uncomfortable, and cameltoe is more like a front wedgie. It’s more unsightly than uncomfortable.
