you are surprised that underwear that is meant to be in your ass crack, rides up it completely... just out of curiosity, what do you think was meant to happen :P?

Yeah they're just like that. You may try g strings instead of thongs, that way the piece that go into your anus is thinner and it might feel better or less like a wedgie. There's one panty called C string that doesn't feel that way.
