Your comment got me thinking: why didn't I?

(Because I didn't draw anything really, some formless lines.)

Is this the fault of consumerism, where we anticipate the penis to come pre-drawn for our immediate gratification?

Or have we witnessed internalized self-censorship?

Or lowered testosterone from work-related stress?

One tiny penis, left undrawn, raised so many questions.
