I'm a 25M straight guy, always been attracted to girls, had multiple relationships and sexual adventures with girls, never been slightly attracted to a guy before. But I got hooked up on porn and it became an addiction and lately I watched a bisexual (MMF) threesome (I was concentrated on the girl but the guys interacted too) after I was confused of having bisexual dream about the same thing, to note that I was shaking of anxiety once I finished (Didn't enjoy it and it felt forced...I even turned the phone away as I was about to finish and the guys interacted and it was the only video I ever watched). Now, I feel extremely shameful and guilty for watching something that doesn't align with my sexuality, and it traumatised me that I've been losing sleep for the last month, whenever I close my eyes the images from the video comes haunting me and it disturbs me a lot. I feel that my life is ruined. I don't know if this porn induced HOCD (Never had OCD before) or just the guilt and shame of letting porn wrap my mind and doing something I've never remotely thought about.
