'Our sex life used to be hot, but now we're in our 50s it's gone stale and tepid'

Dear Coleen,

My husband and I are in our early 50s, we’re both fit and healthy, and look a lot younger than we are. We have two kids, who are young teenagers now and I feel blessed to have such a lovely family life.

My problem is, my husband and I used to have a really good sex life. We never had to try at all really and were so ­compatible in that department and it always happened ­naturally and was always great.
