If women aren't the weaker sex why are we more lenient on them being sexual predators then men?

Recently I have had my eyes opened to the term 'Cougar' which basically is an older woman on the prowl for 'Young meat'. I've noticed that when an older woman goes for a younger man even if she's a man eater then many are still ok with it as we have that 'let the lad have fun and learn a thing or two' attitude but if this is reversed and it is a much older man or men on the prowl for young girls then our mood changes completely from joviality to worry and disgust invoking our protective mode to rear it's head usually. Why is this?

newscruiser, are you comparing 'the graduate' to 'lolita'.
