Me and DH had 3 happy years together and then I went on the contraceptive pill. I didn't realise this at the time but it must have killed my sex drive. We would have sex once every couple of months after I started taking the pill, and at one point went two years without sex. We were only young in our 20s. We had been together 8 years and I found out DH (DP) at the time was having an affair. When I found out he broke down and cried and said he was just grateful for the attention. I broke down and cried too. Despite all my friends telling me to leave him I stayed, I tried to make an effort in the bedroom, and a year later he proposed as he said he never wanted to loose me. We got married and I came off the pill. Within a month I had a massive sex drive! My DH cried one night as he said he had missed being close to me. I felt so bad but at the same time felt angry that he had an affair, I said he should of told me he was unhappy but he said he didn't want to upset me and potentially loose me. It was all such a mess. I tried to brush it under the carpet at the time but coming off the pill made me feel alive with feelings again and so I found it hard to deal with. I never bought it up again though as it just makes us both feel bad and I didn't want to punish him with it constantly when it wouldn't change anything. Apart from that things were going great until I had twins. I have had no sex drive for 3 years. DH doesn't complain even though we have sex about twice a year 
I am just too exhausted and my drive has gone unless I ovulate but even then I'm usually too tired. I constantly worry he will cheat but he tells me he would never do that again and that it was a mistake. I feel insecure though. Even more so because I have gained weight and look a mess. I was inspired to post this after reading another thread about a lady in a sexless marriage, reading it made me feel so bad for her and then it struck me this is what my husband must feel like I love him so much how can I fix this?
