More children would like to be conceived and born into the world, regardless.
Why do you think you can't have children? You don't have to repeat the mistakes of your parents. You can learn from them, right?
Didn't you result from your parents, and that's a "good" thing, right?
The main real purpose of sex, is procreation. Why not let babies happen when they happen, and avoid the magic potions/poison to the body directly, of nasty, experimental, anti-life, anti-nature, contraceptives.
Tell us, for what reasons might you actually like to have children? Can we maybe find some encouragement to get over these fears that can in time pass, especially after children come? If you truly didn't want any children at all, why ask us for advice?
