Confessions:My husband claims I smell and now won't get intimate

My husband and I have beeen together for four years now and our marriage has been good to say the least apart from one disturbing thing. For a bout a year now, he keeps telling me I have  a funny smell. Sometimes I can detect a distant smell, but he makes it sound really bad to the extent that we no longer have foreplay during sex. I have tried everything including using roll on and I shower everyday but he says the smell is still there. I am embarrased by this and have even lost self confidence since I cannot help but wonder how many people actually pick up the smell. I dont know what to do about this but i am worried our intimacy is headed south, please help me.….
