I feel real arousal towards my thoughts it upsets me

Just gonna vent, this never happened to me before during my 20 years alive. Whether it is POCD or not, I have truly lost my sense of self and my innocence. Why of all things did this have to happen. Ive been experiencing more strong groinal responses and mixed feelings of arousal regarding specific thoughts. Its so odd, cause last month none of this happened, it was mainly just anxiety and mental breakdowns. Never did I think I would experience physical sensations as well. Acting on compulsions as well left me feeling absolute confusion, Ive stopped doing that but now I get the urge here and there, and Ive learned to sit with the discomfort. All this leaves me with more questions on whether I will truly get through this or not, or if people will understand my situation. On certain days I feel fine, on other days its sheer terror. I blame myself mainly for this all, It is scary as these images, causing both arousal and terror, only result in me feeling like a shell of my former self

I don’t know if it’s SOOCD. I no longer feel anxious in the moment when I think about women, and it’s like my imagination wants me to think about it and get aroused. I don’t want to be gay, but maybe I am after all. In my life I haven’t been so sexually driven before (when I was living with a man, or when being single) but now all I can think about is having sex with a woman. I don’t want to, but somehow my body does and it feels like my mind have changed to accept it to.. feel so sad This all started around 4 weeks ago..
