You might be on to something. Thinking back to my pre-married period, I did tend to downplay my interest in baseball (and sports generally) when meeting a woman I wanted to impress. And my geeky interest in the statistical side of baseball was a deep dark secret. I felt that was not a good image to present. My interests in wine, travel, even opera were the things I played up.
But I feel this is sort of a safe space where my weird and socially unacceptable interests can be pursued.
