no sex drive

I'm a 39 year old woman and I have no sex drive I could careless about sex but my husband likes sex is there anything out there that will help get my drive back or am I pretty much screwed. I'm afraid when he gets his license back that he will cheat on me we both have cheated on each other in the past. We are over that part of the past. I do love my hubby I just don't care about sex. Yes I have 6 children they range from 21 down to twins that are 9 we have 4 of them living with us 3 of which are full time the oldest goes to his dads every weekend he's 17. Can someone please help we don't have insurance so going to a doc is out of the question may I mention I'm also a sahm
