To answer a question I have been asked a few times.
Yes, both Maasai men and women have holes in both their ears. It forms a major focus for jewelry as the elongated ear lobes are hung with beaded and metal ornaments.
Maasai start this when they are very young.
A slit is made in their ears and wooden plugs are inserted to stretch the slit lobe. As the slit opens more into a hole the plugs increase in size.
