This is so personal that it is hard to ask. I am having a hard time when we have sex. I have these flashes when I see him with her instead of me. Like, whatever he is doing with me, I see him with her instead. It is very vivid, in color, graphic-- I see her blond hair, big blue eyes, and pale rosy flesh. It has made it very hard for me to achieve climax. I have been OK with that for a long while. It felt more important especially early on to have the emotional connection that comes with love-making. I still feel that way. But I just wish it would stop.
