I’m at my wits end

My husband and I have been together 7.5 years married for almost 2 years. We used to have a great sex life and now it’s non-existent. In the last year we’ve had sex 10 times. I have to ask for sex for it to happen. He has low/normal testosterone and I know that can have impact on his libido. Sex shouldn’t be this complicated. He wants children, but how the hell you think that’s gonna happen if we don’t have sex and when we do it’s once. I’m beside myself. Idk how much longer I can keep this up without lashing out
