Does anyone obsess about their partners sexual past?

Does anybody else ruminate uncontrollably about their bf/gfs sexual history? When I'm really down it consumes me! It must be quite masochistic because it almost feels like part of me wants to keep thinking about it and torturing myself with information. I sometimes get this urge to know exactly what was said, where they were, every tiny detail. Were they better than me, dirtier, did it feel better bla bla. Really explicit unwanted thoughts. I know it sounds crazy and psycho! It almost feels as if it is my boyfriend's present or future and I sometimes feel resentful at him for it! (I don't tell him though).. I hate to be that overly jealous clingy girlfriend but I think I am. Recently

Recently my main obsessions have been this and the POCD. My mind darts between the two! I prefer the ROCD one of course
