Smell

I'm a newlywed a month tomorrow. My husband and I were having sex last night and we both noticed a very strong odor during sex.. I have never in my life had a smell not even when I was pregnant... There is no itching, burning, irritation no going to the bath room more often... What can it be please help... I'm to the point now that I don't wanna have sex with my husband due to the smell?
