The Secret of Kissing
The chemistry of romance just gained a new dimension, with revelations that a previously unknown ingredient in salvia increases sex drive. The impact of a first kiss can be life or death to a love affair, but now scientists investigating the biochemistry of kisses say that hormones exchanged during passionate kisses can stimulate sexual attraction.
New findings show saliva in the kiss contains testosterone, so the open–mouthed wet kisses preferred by men may be an unconscious attempt to transfer testosterone and turn the woman on. Don’t make it too sloppy though, or you’ll turn her off.
The exchange of hormones in a kiss may also allow males to assess women’s fertility and estrogen cycle, scientists argue. More than 90 per cent of human societies exchange kisses, but the full story of the hormones exchanged in a simple kiss is still to be told.
Scientists say kissing is a way of assessing our potential mates. They are finding that all kinds of chemical systems are in play in courtship. One study found that 66 percent of women and 59 percent of men say that the quality of the first kiss can kill a relationship.
