I read that you can give candida forth and back in relationships. watch out with french kissing and sex. check if your mouth, if your tongue has a weird colour, than you have candida also in your mouth. if not, than it´s safe to kiss. to be more safe, rinse your mouth with s.th. cleaning from the pharmacy. About sex: Well "smell" yourself, if you´re smelly you also have genital candida.
