Is it normal to want to be humiliated and treated like your worthless?

I am a male and I have a fantasy of being taken by a mistress usually my xwife and turned into a Maid of sorts. I have had dreams about it even where I am dressed in a very lacey and ruffled french maids uniform, black with pink trim or pink with white trim. I am wearing all the appropriate accessories aswell like a matching choker and panties thigh high stockings with bows on them and even the high heels I am wearing match my attire. The dress is locked onto me and I am forced to service a group of people that I know, drinks and stuff, actual maid type things at first. Then I am taken to a stage type area and am told to get on my hands and knees and am secured to the stage. There I am used as a table and my xwife lays on my back and another man has sex with her and she talks about how pathetic I was and how incredible he is. She gets off of my back and then faces me on all fours. While men are using her she is close enough that our faces are touching and she just keeps talking about how amazing it is and how I was never good enough while her forehead is hitting against mine from the force of them having sex with her. While this is going on two men come out and one of them pulls my panties down and inserts his penis into me and hooks us together then lays on my back as the other man proceeds to have anal sex with him. my xwife tells me that I am not worth a fuck from a real man and am nothing but a cum dumpster that's why even men don't want to use me for a fuck just a depository for their cum. He cums inside me and then unattaches himself from me and leaves me there. Once she is finished having sex with the men she releases me from stage and makes me perform oral on the last man that had sex with her and smacks me in the face with his penis. Then she makes me lick all of the mens cum from her where it ran down her legs and lick it out of her. She then tells me to lick the floor clean where it pooled at her knees. While I am doing this she brings in a male dog and the dog mounts me and violates me infront of everyone and she continues to call me names and tell me I am worthless and am good for nothing but taking care of pets as their personal maid.

I am sorry for the length, most of it has appeared in dreams over the past year and my own mind has formed it into one fantasy.
