No sex drive

Do any of you struggle with low sex drive? I never used to be like this but the last two months every time my husband tries to make a move or even touch me I instantly shut it down. I have absolutely no desire to do anything and when I finally have the slightest urge he only wants me to satisfy him and it gets annoying. He told me last night that men need sex and that I need to stop turning him down I’m just never in the mood anymore and I don’t know why. I don’t know what to do
