Corrective Rape in S. Africa

I really don't understand how some men think that raping a lesbian is going to 'cure' them. Surely, any effect it has is going to put them off being near men for life?

It still seems to be happening and on almost epidemic scale in South Africa, and the response of the police appears to have been less than helpful in many cases.

Please keep any comments resonable.
