I'm sorry to admit that I snickered just a little. And the first thing I wondered was if there was any chance that you were pregnant. Since you are, I think it's very likely that the pregnancy has something to do with it. I didn't like the smell of a lot of things while I was pregnant with my triplets. However, there is also the real possibility that your husband could have a medical problem. My oldest child "smells weird" to me when he has a fever. And I always know when my kids have strep because that has a distinct odor to me as well. My father-in-law is a doctor and he thinks I'm crazy... But every time I say that one of the kids has strep, I'm right! He has quit arguing with me! Could your hubby have a sinus infection or something?
