Possibility 1) You're a sport. (and so am I).
Possibility 2) Recessive gene for not wanting children gives heterozygote advantage.

Possibility 4) Genes for other pro-survival traits linked to recessive non-breeding gene.
Possibility 5) Environmental change resulting in some gene variants formerly expressed as "wanting children" now expressed as "not wanting children".
