It's been a whole month since we had sex. And that was about a month after the last time we'd done it too. We are averaging about once a month- 6 weeks at the moment 
He doesn't see an issue, he says he's tired, not in the mood etc. He spends his free time playing xbox when he's at home. When I ask he tells me to use my toy
he gets home from work about an hour before me so I'm convinced he watches porn and masturbates in this time.
I'm fed up. I'm not ridiculously horny or something but I do like the closeness sex brings. We only moved in together last year and sex became rarer after that. Is that normal? Is this what a long term cohabitation relationship is like?
