And can we please get rid of this notion that verbal consent means "signed in triplicate, with the signatures witnessed" nonsense, or that it somehow "destroys the mood"? If you can't manage to say "Do you want to have sex?" in a way that is a sexy come on (with choice of words picked according to your partner's personality - some may respond to an earthy "fancy a fuck?", others to a "do you want me inside you?" etc.), then perhaps you aren't grown up enough to be having sex.
I can't believe how many men out there must be having really, really crap sex all the time, if they honestly don't know what enthusiastic participation feels like! That somehow we're stuck in a time warp where a lot of men think women are sexual gatekeepers, who reluctantly agree to sex for other reasons (conception, keeping a man in a relationship, I dunno, plain masochism, maybe?) and then lie back and think of England for the duration.
