Sex File: I'm doing all the work in bed and he never makes the first move

There could be any number of reasons that your partner has lost interest in having sex

I've been with my boyfriend for five years. It's a strong and loving relationship - but one thing bothers me. We only have sex when I make the first move. Enthusiastic though he is once we are up and running, he is never interested in initiating it. Can you suggest anything?

At the beginning of a relationship no one needs to think about initiating - you eat, breathe, have sex and sleep, then wake up and do it all over again. As it matures, the frenzied coupling tails off, and after five years it is, I'm afraid, increasingly rare for partners to find themselves in the same mood at the same time in the same place.
