I agree, Solalux, when I was at uni,and in my 20's many women said they never wanted them, but subsequently had them.
Men, never said that, but then again, kids were never really a discussion at college !
Nor really come to think about it, with my various boyfriends at that time, because I never discussed it - believing I would have kids 'one day'.
However as I got older,into my 30's I realized I had never discussed it, because I didn't really want them at all, and when I married, and felt the immense pressure to procreate, my husband didn't want them either

It's hard to differentiate a true desire not to have kids, until someone gets past the age of childbearing, then I believe it.
- How many women do we all know who get to early 40's and suddenly have a child they never wanted...
There are only 2 women that I know are truely cf . I met them when I was early 30's.
One of them goes away on week long holidays with friends at least once a year, and she says by the end of the week she can't wait to get home, close the door, and get back to pleasing herself.
- noone to argue with, watching whatever she wants on tv, eating what she wants, whenever she wants etc.
I always thought it was sad she lived alone, but as I got older, I realized how completely contented she is - loves her life, wouldn't want it any other way.
The other is my age, and her and hubby have great holidays / short breaks, have good jobs, a great house and plenty money to do whatever they want.
