We've been together 4yrs. Great relationship for the 1st year. He had a back operation which has lead us into a sexless relationship due to his depression and medication he was taking. We haven't had sex in 3yrs. I've always had a thought that we'd get things going again but it hasn't. We have no connection. It's put a big strain on our relationship as I've become increasingly insecure over it all, even more now because I asked him why we don't have sex (not a topic we talk about) his reply was a light went out because he didn't like the feel of my saggy bum (I've put 1 stone of weight on due to HRT) He says he couldn't tell me before because he didn't want to hurt me as he loves me. I'm absolutely mortified and not sure I can carry on. HELP...I don't know what to do
