I've found pregnant women attractive for nearly my whole life. I've accepted that I'm a maiesiophile, and I adore sexy pregnant women.

I agree with the idea that the view could have some genetic underpinnings. I heard my father more than once years ago point out to my mother about catching sight of pregnant women on television. I was like, "What?" at the time, but in retrospect he could very well have been a maiesiophile and my mother could have been aware of it. It may have been one of those things they shared that people who are that close just understand between each other but don't talk about otherwise. It makes sense given the circumstances anyway.

First time i feel attracted to pregnant woman when i was six. I was just an innocent kid who knew nothing about sex, and love to look at her!
I think heredity have something to do with it. Maybe without our awareness, our parents had maiesiophilia as well.

I was around my mom when she was pregnant with my younger sibling, who's less than two years younger than I am. I remember placing my head on her belly and saying, "hi, baby." I also remember my mom showing me episodes of A Baby Story on TLC when I was four or so. I'm guessing that my fetish comes from a combination of these two experiences.
