Is this only me, I get sexual images about people that aren’t appropriate for it (family, young people) and the worst thing is they’re detailed

I feel like one of the worst things about ocd are the disturbing images or the ‘little movies’ that replay in your head over and over again. I have the worst sexual images with one of my family members that actually so bad that I can’t even look in the mirror. And it’s even worse that I have a lovely boyfriend and I’m so disgusted of myself that I feel like I don’t deserve him and I feel like I can’t be with him because of these thoughts, even he is the most precious thing in my life. These sexual images are so horrible and what makes it even worse that in these pictures I always see myself as someone who enjoys it. I know how to deal with this anymore. My mind is trying to convince me that that I actually like these images and thoughts and this is the hardest part, that I’m doubting myself. These images pop up in my head so naturally that I always question myself if I actually don’t like it why it comes so naturally or how can my brain picture things like this if I don’t like it. It’s getting worse day by day. It’s in my head 24/7, can’t concentrate on anything else, I can’t eat because I’m constantly throwing up. And my mom has to sleep with me every night because I’m so disturbed by my own mind. My parents know that there’s something wrong with me, they think I’m depressed but sadly It’s not something I can talk openly about with them. I’m seeing a therapist next week but I’m genuinely scared to open up about these thoughts that I’m having.

Am I the only one who experiences this, or is it more common than I think? Sometimes, I find myself imagining what a couple’s sex life might look like, or what a person’s body might be like. I think it’s driven by curiosity, and I focus on it for a few seconds. When it comes to family members, teenagers, or anyone I feel uncomfortable imagining in this way, I used to be able to shake it off as an intrusive thought. But lately, I can’t seem to let go of it anymore. I’ve become used to the anxiety, but I’m stuck questioning what this means about me, especially since I’ve taken time to think about it. This is really stressing me out because I feel like a pervert. I’m hoping that this is something more common than I realize and that OCD is just distorting something. I feel like I really need some insight here. Any advice?

Does anyone else when they have the thoughts, they feel against it, but they still get arousal or tenglings sensations in the groinal area? Because this is what I experienced today and I feel like crap. This is going to be very triggering for a lot of you, but there are a lot of times that I notice things from kids. For example, there is a thirteen year old kid who looks very developed for her age, and I take notice of (and this already sounds creepy to me) her chest. Today with my thoughts, I imagined as if I were touching it, and although I usually "no no or "I don't want to do that", she is a kid, etc., I still get responses in my groinal area, and It felt very real. Even now, I feel as though I am faking it, even though I groan 😮‍💨 from it, and feel as though I am a fraud. Does anyone relate?
