Did you ask her why? Sometimes one does not take good care of your teeth and tongue (hygiene - brushing etc) and then your partner feels uncomfortable. It can also be that you have digestive problems which can make your mouth smell bad or you eat strong foods e.g. garlic and chillies. Sometimes when a person smokes a lot or even drink alcohol, this type of intimate kissing is just not acceptable.Sometimes it is just that if you do the tongue-thing that you have too much saliva and that is also not nice. It may also be that she had a bad experience as an adult or as a child with a tongue and there for does not like it... Try and make sure all these things are in place and then discuss with her an alternative.Deidre - SASHA
