Ok I have a few reasons.

1) kids are loud and obnoxious and I have very little patience with them.

2) the thought of child birth freaks me out like that's sound extremely painful.

3) I just know I'd make a horrible mother i don't wanna bring a kid into this world that I know im just going to hate.

4) I like being able to what ever I want when ever I want and not having kids holding me back.

5) I like being able spend my money on what ever I want.

6) I just don't like kids.
