You know, I've considered that a possibility. And believe it or not, we have even discussed this and he thought it sounded ridiculous, and assured me that it wasn't the case.
However...there may be something there to which he may be in denial.
You can get a clue from his parents / upbringing. If he had a strongly conservative upbringing, with a 'proper,' upstanding mother (remember the posts where I discuss my own puritan mother?), then the "Nice Girls Don't" pathogenic belief may be nicely embedded, even if he doesn't realize it on the surface.
