My boyfriend moved in with me about seven years ago. Since then, I swear that my armpit and other sweat odors have changed and are more like his. Is it possible that his pit-bacteria have colonized me? Thanks.

Hey Dinah, this is definitely possible. I have heard this case from quite some people and it even happened to me. Our research shows that malodors are more or less in the family, partly due to your genes, but also via transfer of microbiota. Nothing to worry about though. But yes, your body odor might change a little… Best, Chris
