Reaching for a mint probably seems logical if you think kissing may be in your future, but the menthol in mint reduces testosterone, therefore lowering male libido. Mint can also allow more air to enter the body causing frequent burping, which isn’t exactly a turn-on. Mint tea is a better choice to fight bad breath, since it has a lower level of menthol. Alternatively, you could use other natural herbs or simply brush your teeth.
