Do the secretions a wife experiences after her husband kisses her invalidate her fast?

The fast is not invalidated by the emission of pre-seminal fluid (madhy). However, if semen (maniy) is emitted following a husband kissing his wife, her fast is invalidated thereby. It is not permissible for a fasting person to expose their fast to invalidation. If kissing arouses desire, then it is not permissible for a fasting person to do it.
