Kissing wet stimulates interest in sex

When you share a kiss with your man, you reveal a lot more than any just passion.
US scientists have found that modern man uses smooch to pick up traces of estrogen in woman's saliva and thus gauge her fertility.
Anthropologist Helen Fisher of Ruters University says that such behaviour may explain why men like wet kisses with more tongue action.Fisher said that wet kisses could also be an unconscious attempt to transfer testosterone to woman, which would stimulate her sexual interest.
