I believe if it was a one-off, I suppose she could have got away with the double-standard more effectively. However, the woman had sex with him more than once and performed oral sex on him a multitude of times - whichever way you look at it, she was wanting it bipolar or not, lol.
Now I believe if a man did that to a 14 year old girl (not that I believe it is acceptable under any circumstances), he would get the book thrown at him and would be put on a sex offenders list for 'x' amount of years and a good chance he will be thrown in prison.
The difference is, if a boy has sex, there are no repercussions to the action because he can't get pregnant and therefore it is classed as pleasure. If a girl has sex, there is a big repercussion to the action because she can get pregnant and is classed as rape or whatever.
My point is not that I condone this situation whichever gender is affected. My point is that, in the interests of consistency, this woman should get a stiffer sentence (pardon the pun, lol).
