If you're not in the mood, you're not in the mood. Can't be helped. If it's often the case that the spirit is willing but the body isn't cooperating, well then you might want to talk to the doc.

If my guy's not interested and I'm absolutely desperate, sometimes he'll be a doll and help me get off (which, incidently, sometimes changes his mood...he does love listening to me). Other times, he just reminds me where we keep the vibrators.

But you shouldn't feel bad about it, not even Pixies are ready and willing 24/7.
