Libidos can easily downshift after becoming sober. And it sounds like you had a relatively libido to start with. So I wouldn’t put too much pressure on yourself. Keep letting your husband initiate cuz most men don’t mind that and will keep asking unless maybe you’re constantly turning them down. Also if you want to be the initiator, maybe try to plan. I know it sounds unsexy to literally plan sex but just make up some reason as to why on X day you’re gonna come home from work/stressful meeting/long errands whatever and just gonna need his dick. Then you got a couple days to talk about how much your gonna need it, dirty talk about all the places and positions etc. put that energy into the air
