Married with no sex life

I’ve been married to my husband for 8 years. I think he is an amazing man and father. He’s never really had a big libido but now we are lucky if we have sex once a month. We both have full time jobs, are tired and have two young kids. He has to take viagra now and I just really miss having spontaneous sex. I miss feeling wanted and desired. He tells me he loves me all the time and that he’s attracted to me. I find it hard to be attracted to him when his idea of having sex is laying there passively thinking it’s on me to come over and make him hard. I just lose all sexual attraction. I want aggression, passion, masculinity. I want to feel desired. I opened up to him about this and he was receptive only to just lay there passively. It sucks. I can’t imagine continuing to have the sex life we do for the next ten years. But aside from our awful sex life we have the sweetest family and love all being together. I know opening up to him has hurt him but I just want to feel more alive in the bedroom. I have been thinking of breast augmentation hoping it might spice things up. I’m just kind of desperate to make it work.
