I have a terrible case of oneitis. I'm embarrassed to even be typing this but I need some serious fucking help. It's gotten so bad that I can't even enjoy rough sex with other girls. Whenever I'm fucking one of my plates roughly, I imagine another guy doing the same thing to my oneitis and I lose my hard-on. When I'm studying, I keep imagining her blowing/fucking other dudes in front of me who are bigger, stronger than me, and have bigger dicks or her sending me pics of another guys dick/jizz in her mouth. Sometimes it disgusts me, sometimes it arouses me. I'm 6'0, been lifting for 1.5+ yr, and have an above average dick. I've never had cuckold fantasies in my life before her but I used to watch a lot of porn. I'm currently spinning 3 plates and I don't want to get cucked by any of them in the slightest.

The worst part is that I can get with my oneitis easily. I've fucked her about a million times but can't right now because we're not in the same city. I've been in denial that I have oneitis for her for about 1 year because whenever I fuck her the oneitis goes away. My oneitis is caused by insecurity or fear that I can't have her so when I do fuck her it goes away. I'm essentially addicted to her because of the validation I get from fucking her.

I've fucked 5 girls since her, 3 of them being objectively hotter than her. I still can't get her and this cuckold shit out of my head.

Why is this happening to me? How do I get this cuck shit out of my head? It's fucking with my self confidence and masculinity.
