Is it a matter of she can't get any other guy because she's a hag or is it about control? Often sex offenders do what they do because they feel it gives them power over someone. Most of these women are teachers. Who has more power over a kid than a tacher, think about it.
I think the double standard wil always be there, but at the same time if it was my son, i'd be hunting someone down.
And Chuck Norris would help me.
