penile spines

A feature of the feline penis and other mammals (such as fossa, spotted hyena and echidna) as well as some birds and even insects, where sharp, backward-facing spines protrude from the shaft and head.

Sex for cats may be very painful because of these barbs, but even though it may be painful, these hook-like barbs are essential in causing the cat's pussy to be stimulated in a particular way so as to release the eggs.

For dildos, use the barbed_dildo tag instead.
