CF

Childfree - Voluntary childlessness, also called being childfree, describes the voluntary choice not to have children. In most societies and for most of human history, choosing not to have children was both difficult and undesirable.

The girl I met at the bar yesterday is CF, we actually might match!

My parents disapprove of me being CF, but my body my choice!

I finally have enough money to get a vasectomy so I'll always stay CF
