Which male structure is homologous to the clitoris?

The penis.

Yes. All of those nerves in the penis are bundled into the clitoris. *That* is

Actually the entire penis!

The head of the clitoris is equal to the head of the pinis, the curx (sp) of the
clitoris is equal to the shaft of the penis.

actually it's the HEAD of the penis. the clitoris has the most nerve endings, so
does the head.
The glans or head of the penis.
The middle toe on your left foot I think.
