Have name changed.
My dh has suffered from depression for last 4 years following sudden deaths of his parents. Whilst he was depressed, he had no libido at all and we went 2 years without any sex. Before that I had PND and we didn't have a lot of sex. Before dd (6) we were like rabbits!!
He's been slowly returning to his normal self (mood wise) over last few months and we have had sex a couple of times - about once a month. The big problem is that he works shifts so we rarely see each other, he's a night owl when at home and other times we're just way too knackered!! He thinks we should 'schedule' sex but I hate the idea of having to plan it and it feeling contrived, or one of us not feeling in the mood on the planned evening etc etc. I am not 100% happy with my body at the moment so don't instigate sex like I used to and often worry he finds me ugly and unattractive, but he assures me this is in my head. He's not (never really has been) a hugely physically affectionate man outside of sex, and I think if I got more cuddles and kisses I may feel less concerned. He shows me he cares in many other ways but I am very physically affectionate and sometimes feel only affection I get is from dd.
When we have sex it's great, really great 
and we're happier as a couple than have been in long time now his depression is improving.
I am fairly sure I am over thinking this but how do we get our groove back!?!
