The second is that size works as a signal, attracting potential mates and intimidating rivals. In evolutionary terms, the penis is big because it is meant to be noticed.

That finding lands awkwardly in a world that has spent centuries hiding, shrinking, censoring or symbolically neutralising the penis whenever it becomes too visible.

A single object captures this tension between biological display and cultural embarrassment: the fig leaf.

The fig leaf’s story begins, as so many Western stories do, in Genesis. Adam and Eve eat from the tree of knowledge, realise they are naked, and stitch fig leaves together to cover themselves. Nakedness becomes linked with moral awareness, guilt and self-consciousness.
