Misophobia with sister

What should I do? I already talked to my mom and we worked it out, but OCD won't leave it alone. Here is the situation: OCD is ruining my relationship with my family. Along with my porn addiction, I can't see innocent interactions without malice or wondering if it's appropriate. My mom and sister always had this game of slapping each other's butts, and I always found it funny, but these days I have been feeling uncomfortable about it and asked them to stop. My OCD is trying to convince me that my mom has said me, because one time she said that if she were a boy, she would date me and one time she just blurted out "marry me" I told her I hated that, she apologized and said she didn't mean it and never did it again. A lot of the things she said these days I wonder if they're appropriate, like commenting on my body, it was things like "Your butt is smaller", because I lost a lot of weight. And these days she was talking to my sister and she said that her breasts are growing and my sister was like "I know😝😝" and she poked the side of her breasts and they just laughed. I asked them about it and my sister says that she sees no problem at all. I remember that when I started puberty, my mom would ask to touch my breasts, she never actually touched, but she was afraid cuz when she was in puberty she said her breasts hurt a lot, and she was always like "You are growing so much, they are cute." And I would get sad cuz mine's weren't big as hers. I am spiraling and my mom is the most sweet person in the world, she supports me in EVERYTHING and has always taught me to set boundaries and stand up for myself, she always respected my boundaries and talked to me about delicate things and I always felt comfortable to walk around naked or ask her ANYTHING. But remembering these things are making me question her behavior, when I know she did not mean harm and I notice that 89% of every mom I met, are like her, she is probably like that because that's how she was created, and Honestly, if she did not mean any harm then everything is fine. As I said I didn't felt uncomfortable, but OCD is like "You should feel uncomfortable because that is inappropriate behavior." It's just that I didn't care for those things I even once asked to touch my mother's breasts when I was younger cuz hers were so different and I was like "What?!?!? why are we different?" and she was like "ok" and I stopped to think that I literally used to breastfeed on them and I was " 😮😮" like, I feel bad nowdays but I was curious, and my mom just said "It's okay, but If you did it out of malice then it would be wrong and I would be uncomfy." Now OCD is making me not want to be near my mom when she literally respects my boundaries, I said I didn't want her to do these things again and she agreed without even a second thought.

when I watch my sister and she does something around her lips, I don't know why she has this habit of touching them and scratching them, I feel that it attracts me or excites me. I don't really know how it stops..if it stops..if it's ocd...I can't spend normal time anymore…I am alone in this..?!

My little sister is 13 we’ve taken her to a child psychologist and she was diagnosed with OCD and social anxiety and I believe germaphobia. The psychologist said that he can’t properly diagnose her with autism until her anxiety symptoms are treated. But I am very positive that she is also autistic as I am autistic and know the symptoms vary well. She was given a medication at a low dose, I don’t remember what kind, she had been taking it even tho she did not want to for a couple of months. It seemed to be helping her anxiety immensely but I believe she is scared of how the medication changes how she feels and she doesn’t like the taste. So they switched medications and that one was even worse because the taste was too strong she didn’t even try it for more than a day so there’s no way of knowing if that one was better for her or not. These are both liquid medications btw we used juice for her to drink it. Since then she hasn’t taken any medication and she has said that she doesn’t want to. We can’t force her to take the medication as that would obviously be counter productive. But since then her ocd and germaphobia have gotten progressively worse. On top of not wanting medication she doesn’t like the idea of using any coping skills like deep breaths or breathing exercises to calm down and doesn’t like the idea when I talk about ERP or therapy or any kind of treatment that could help. It seems all the ideas either make her uncomfortable or scare her. I fear somewhat that my own ocd compulsions have made her think that this is normal and doesn’t need treatment and I don’t know what to do to help understand that treatment and change isn’t scary. I also fear that I’m not approaching this right and my mom doesn’t understand ocd like I do so I feel like it falls on me to help her through this and help my mom understand what we need to do to help her. I’m sorry this is so long. thank you for reading this. She’s really struggling and it’s affecting my own mental health too and I don’t know what to do. If anyone has any tips or advice please that’s all I’m asking for.
