I totally jumped for joy when I was told it was highly unlikely I would ever conceive. And if I didn't, I probably would miscarry before 10 weeks. I'm still on birth control, just to lessen the odds. No way I ever want to be a parent, and pregnancy really grosses me out. So I know exactly what I'm giving up, even being in a position where it's highly unlikely anyway. And I'm happy with it. Thrilled.
If others want to have kids, go for it. But just because you feel like you have that right, don't call the rest of us out for not wanting any or questioning the reasoning behind doing such things.
Two way street, folks.
