Hi @pollypower! The answer depends on the manufacturer, so its worth checking the box to see if the flavoured condom should only be used for oral sex. Some lubricants may also contain glycerin- which is a sugar. Whilst there’s no hard research evidence, some people do have skin sensitivities to certain condoms & lubricants which may cause a yeast infections. What’s the best flavour? Chocolate, banana or licorice???
