Ok, let her shove a large dildo up your arse and work away at you for 20 minutes. If you love it then she should olblige and let you do the same.

Really, I wonder about men, there are so many threads on "how do I convince so and so to have anal". How dare anyone try and force another to have something shoved up their butt. Ask once, if she says no, shut the fuck up forever. As a woman who has been pressured, I know. Shut up!
