As someone else mentioned, what you eat (ie coffee) can have a big influence on how you smell. Aparently vegetarians have a different smell, and I imagine the amount of sugar and dairy products can influence it in a way too. Maybe do some research on this aspect of it.

Or give your partner something strong smelling to put on the skin directly under his nostrils (like a diluted essential oil or a bit of tiger balm {as long as he doesn't get it on your muscous membranes}). Thank should block out any other smell in the room.
