does anybody else have trouble with which way you wear certain panties?

Obviously some are clear to tell, but some thongs and "cheeky" style panties will trip me up. Im used to boyshorts and the tag being on the back, but some put it on the front and some have none at all! Maybe im just silly and cant figure out basic panties, but I was wondering if anyone else has this problem and how you figure it out before putting them on backwards
