Husband NEVER wants to have sex

Starting to get really frustrated with my husband. We haven’t had sex in almost 2 years. We lost a baby early on in our marriage so we didn’t have sex for a while after that because I wasn’t ready. I’ve approached the topic of sex with him numerous times and it literally gets no where. I’ve said I might as well by a sex toy to satisfy my needs. I don’t understand what’s wrong with me? Why wouldn’t he want to have sex with his wife and for those wondering I know he’s NOT cheating on me. What else can I do???
