Sex life has diminished

My sex life with my man has almost completely diminished we mess around like 2 times a month if I’m lucky. I feel like he doesn’t find me attractive anymore. I had our daughter 14 months ago and I never lost the weight I gained. I don’t even like being naked anymore. He won’t let us do anything without the lights being turned off. And I’m at a loss. I just don’t know I am trying everything to lose the weight keto, working out, jogging, everything and I’ve only lost 10 pounds 😔 can any one talk to me and let me know maybe it’s not me that is the issue?
