I'm not going to blame the victim here. If she felt it was her right to call him out publicly for this scenario then she must feel pretty strongly about it. I'll give her the benefit of the doubt, because I think that is one of the main messages of this movement more than anything. We must give credence to the allegations and not just slide them under the rug.
That being said, I've known more than a few women who would rather a man be more dominant. They don't want to be asked to be kissed; they want to be kissed. They don't want to ask to be ravaged; they want you to take control and show them you are a man.
Obviously no means no. There's no getting around that and anyone who says otherwise and makes a girl feel guilty for giving him "blue balls" needs to take a quick trip to the bathroom to freshen up or just have the emotional dignity to understand that sex is a consensual event no matter the time or relationship between the partners.
But...you can not deny that stories such as this one make an already uncomfortable grey area that much more prone to awkwardness. I for one don't want some girl blowing up Twitter or Facebook with allegations so I'll steer clear and make sure she makes the first move. It'll be a lonely road, but I'd rather have the happy company of myself than suffer the humiliation of an awkward, misread tryst that results in me being ostracized by my closest friends.
