I'm "romantic about sex" and I'm also NOT a career woman.
I simply have no desire to be a mother.
I love some of my friend's children, but can only take them in small doses. I'm always very happy to go back home to my quiet space with our two cats.
I worked with special needs children and I absolutely adored them and loved working with them, but kept thinking how I could never have a child, let alone a special needs child who would be dependent on me until the day I die. (Ater all, there is absolutely no guarantee that you will end up with a healthy child). I've seen what that does to a couple and to the rest of the family. I would come home from work absolutely drained and would ponder: "Imagine if, after being with the children at school all day, I now had to take care of my own family: cook, homework, bath, laundry, etc". There's no way I could do that and stay sane.
I also have suffered from depression on and off since being a teenager plus, I never had the urge to run to a baby like all the girls around me nor did I ever want to babysit when I was younger (I felt like a misfit, to be honest, until I found this forum three years ago!). Funny though because children are drawn to me and I'm very good with them... How does that work? So of course I always hear ("Oh you're so good with children! You'd make such a great mother!) So annoying.
