Side Effect of Porn: Imagining Your Partner w Others During Sex

Has anyone else experienced not being able to orgasm from a regular sexual encounter with their partner unless you imagine your partner having sex with someone else? My girlfriend unfortunately told me about some of her past sexual exploits in detail when we were early in our relationship. I’m pretty visual and this, coupled with my use of porn, lead to an inibility to bond with her sexually because I’d imagine her with other men. Finally, this lead to me having trust issues with her because, though on a rational level I trusted her, having seen her w different men in my head really messed me up. We finally broke up last week because I just couldn’t really trust her. There were other issues obviously but this was a problem. Can anyone relate?
