"Everytime I watch a film with my boyfriend he makes comments about how fit the girls in it are. Then after the film talks explicitly about their boobs. Am I over reacting, or is there a way to stop him doing it? I don't want 'Schindlers List' to be the only film we can watch together. Fuck it, we can't even watch that - the shower scenes."
Tell him you've decided to experiment with lesbianism and to call you if he wants to talk about hot knockers, because he damn sure won't be seeing yours anytime soon. Alternatively, start watching gay porn.
