Some people have this idea that they have to be "in the mood" to have sex, but like many other activities sometimes you start doing something and you find that after a few minutes you begin to enjoy yourself. If you physically can't that's another problem, but for some this can be solved by setting a reminder to initiate sex from time to time. Really as a couple you should set aside some time to be physically intimate (not necessarily have sex) with each other on a regular basis, if you did that you may find the problem sort of solves itself.
