You have chosen to be careful and avoid situations in which you will be responsible for childrearing. This is absolutely a reasonable decision.

When his sister was arrested for drug abuse, my coworker had to choose between letting his niece, whom he'd been enamored with, enter the broken US foster system, or whether to go e up bachelorhood and provide a home for her.

When my wife's best friend found she was pregnant at 18 months, she had to decide whether to carry this child to term or have an abortion. She was and remains very pro-choice, but that's a very different choice when you can feel the baby kicking inside you.

The choice you've made was yours to make, and is perfectly valid. But don't assume everyone gets to make the same choices you do.
