For them, sex is a release. Have some sex. Sex and some drugs. Sex is merely a tool to get through the tough times and release some of your pent up energy. And hell, sometimes you can bring a friend, and tag team.
Sex is a game or an appointment.
And sex is a job. Go to any major city and you can see porno bars, prostitutes, and pimps. For a small amount of money, you can talk for a little bit and then have sex, or just start in a pumpin'. Whores work double time as psychologists, and the only pill they prescribe is a muscle relaxant. But, just as people can not see my point of view about love and sex, I can not see the pleasure obtained in sex with someone you don't even know.
