I hope I am not overinterpreting or intruding... but wow - bleeding abrasions on your labia minora - sounds like a serious posture or bike fit issue.
Your weight is supposed to be on your ischial tuberosities - the sit bones - not on your vaginal area. Also, your hips are not supposed to move, i.e. there should not be friction with every pedal revolution. Check your saddle height and fore-aft position, as well as tucking your belly in/bending in the lower back such that you sit on the sit bones.
For protection of the area most use a greasy cream (I've also used diaper cream for the last 2 years but for very long rides, just found something even greasier and am also trying an official "seat cream"). I understand that this mostly protects your skin from sweat and the resulting rashes, severe friction and weight distribution issues have to be solved via bike fit.
I have tried washing the chamois with shampoo before it goes in the washer. In my experience, the grease comes off.
I do not use a dryer so maybe it's too late for your shorts now; but never mind, shorts are a consumable in cycling and no one will see any stains remaining.
Rest assured even with a stain, they are still hygienic.
p.s. you are riding commando .... nekkid.... in your shorts aren't you?
