It's been so interesting reading this thread. I got married at 23 to my first love and sex was always an issue. From the start he wasn't interested really but we would have sex sporadically. We seemed to go in cycles where I'd get really upset about it, wanted to end things, he swore things would change, they would for a short while then it would slide back down.
Like others said it isn't just the sex it's the loss of intimacy and never feeling desirable. I used to periodically develop intense crushes on people (generally from work) and spend time constantly fantasising about them. Looking back I think it was a way for me to try to get my desire for intimacy met
He would say he didn't want sex as he didn't fancy me as I was overweight which was terrible for my self esteem. I lost a lot of weight and he still felt the same, I felt angry then as up until then I had felt it was my fault for being fat.
I ended up getting close to a man at work and we had an emotional affair. Nothing happened physically but feeling desired again was unbelievable! I knew I had to end the marriage then. It opened my eyes to what I was missing and that other people could want me.
I ended the marriage (nothing ever happened with the guy at work ) and then 6 months later I met my current husband. We had amazing sexual chemistry from the start and still have an active sex life now. It's so different. We've been together 10 years now
I have never regretted leaving even though being a single mum on benefits was tough.
Just thought my story might help people see there is life on the other side of these relationships
