LOL I'm the creepy one, but you're asking about my sex life. LMAO!!
Look up websites about being childfree by choice if you need to learn more.
Being childfree by choice means that you're not barren or sterile, so you CHOOSE not to have kids.
I get asked questions about this all the time and it's funny people think that it's ok to ask about your sex life. I don't care because I'm an open book, but I just think it's funny.
It's like me going up to a family of 5 asking them why they need more than one kid.
And since you're curious, no I have never "slipped one pass the goalie".
