If the amount of information obtained from a partner's words is '1', then the amount of information obtained from saliva is as much as '200 million'. Humans feel comfortable with the scent of partners who have different immune systems (MHC genes), which is said to increase the likelihood of leaving healthier offspring. Kissing is also a place for exchanging scent information and instinctively choosing a partner. Having every part of your body licked and enveloped in saliva causes large amounts of 'happy hormones' like endorphins and serotonin to be secreted, with some even claiming it makes you five years younger. You should understand by now. Drowning in saliva, wrapped in a woman's mucous membrane with tongue action, and finally reaching the peak of pleasure with a handjob... There can't be any greater happiness. It has to be this way.
