Lets take this opportunity and write up some ideas. They will differ in intensity by a lot. I do not expect you to do all of them but I would be pleasantly surprised.
1.1 Take some red lipstick an write "whore" on your face with the o being your mouth.
1.2 Take some red lipstick an write "whore" on your ass with the o being your asshole.
1.3 Take a marker and write "pathetic" on your tits, "needy" next to your cunt, "cum dump" on your tummy with arrows to your ass, cunt and mouth.
1.4 Take a marker and write "please hit me", "rape toy", "pain slut", "please hurt me", "abuse me", "stupid", "worthless", "anal whore" on yourself.
1.5 (extra) Go in front of a mirror and find all the flaws you have. Point an arrow on each flaw and give it a number. Write a list with all the flaws and describe for each how your body is flawed.
1.6 (extra) Go take measurements of the girth of your arms, legs, chest, tummy, waist and write your measurements on your body.
2.1 Go behave like the bitch you are. Get on all fours, stop speaking and act like a dog for an hour. You can bark, you can squirm but for that hour you are a dog.
2.2 Go behave like the bitch you are, get into your shower and take a piss like a dog.
2.3 Go behave like the bitch you are and eat your food from a plate of the floor, not using your hands. You need water with your meal? Put it in a bowl and drink it from the floor not using your hands.
3.1 Fetch a toy to plug your ass with. Plug it and stay plugged for an hour. In that hour do chores while plugged.
3.1.1 (extra) Once that hour is over, go be a good anal slut and suck that plug clean.
3.2 Fetch a toy to fuck your ass with. Big enough to hurt, small enough to endure it for half an hour. Go fuck your ass for half an hour and rub your clit to edge. When you get on edge, say "I am an anal slut, I love anal." and cool off a bit just to repeat.
3.2.1 (extra) Once that half an hour is done, go be a good anal slut and suck that toy clean.
3.2.2 (extra) shove 3 fingers deep up your wet cunt and lick them clean to show yourself how much your cunt liked this.
4.1 Go to your toilet and lick the seat, drag your tongue one there one time all around.
4.2 Go to your toilet and lick the bowl, drag your tongue one there one time all around.
4.3 Go to your toilet and get your head in there. Go flush, get your hair and face wet with toilet water.
4.3.1 (extra) 4.3 but take a piss first.
4.3.2 (extra) 4.3 but take a piss and shit first.
4.4/3.3 Be a good bitch and drink out of the toilet. You can flush before you do it.
4.4.1/3.3.1 (extra) 4.4/3.3 but take a piss first and don't flush.
That is a bunch. I myself am a sadist so causing pain comes even more naturally to me but I think this is a good write-up to start with.
Happy self-degrading
