No sex

Hey yall i need help .. me and my so have been together for six year and recently moved in together. It seems like he has lost interest in sex the moment him and I moved in. We probably only have sex 1-2 times a week on the weekends. I respect him saying he doesn't feel like having sex. I just dont understand why only wanting to do it on the weekends 😕 its not like he falls asleep early or anything but he still watches porn and jacks off. Makes me feel insecure about myself. Idk what do yall think?
