It’s not that I want anyone else, but I just can’t wait. I really miss the fabulous sex life we used to have together

I have been married for 31 years. I love my husband and I know he is crazy about me, but we have a problem: we’re not having sex and I don’t understand why.

We used to have the best and most fabulous sex life – creative, passionate – but now we haven’t had sex at all for nearly three years (we’re both in our 50s). I really miss it and I have spoken to him about it. He misses sex, too, but he doesn’t know what’s happening to him (he’s had blood tests and everything is OK).
