My sex life has dropped off. Is my marriage at risk?

How often you have sex is not what counts, what really matters is the attention that you pay to each other

The question I have been with my husband for 10 years. We have two children and are very happy and enjoy being together. But one area does bother me: our sex life has dwindled, particularly since we had children. We used to have sex daily and it was great. But, as time went on and our children arrived, I find that we're just too tired to have sex as often.

Our first child was born prematurely and spent time in neonatal intensive care. We both found that difficult and I think that I am still traumatised by it. My husband says it's the past and that we should not dwell on that trauma. He's right, but I can't seem to help it.
