If reports are to be believed, Hollywood actress Julia Roberts' fetish for peanut butter sandwiches left her with bad breath, making it difficult to shoot love scenes with co-star Clive Owen in "Duplicity". So, she used to freshen up before filming the intimate scenes.
For those aware of their bad breath, dental expert Rachana Doshi suggests the use of a mouthwash as it gives "a fresh breath every time you use it and also causes less germ buildup".
It could be a French kiss or a woodpecker kiss; so another important tip is to ensure your lips aren't dry. Moisten them.
