Paris, France - People who are nervous about public speaking should first have penetrative sex to ease the stress, says an unusual study. Stuart Brody, a psychologist at Britain's University of Paisley, compared the impact of different sexual activities on blood pressure when a person later underwent a stressful experience.
He asked 24 women and 22 men to keep a diary of their sexual activities for two weeks. The volunteers then underwent a stressful ordeal that involved making a speech in public and doing mental arithmetic out loud. The study, to be published in Saturday's New Scientist, revealed volunteers who had had penetrative sex during the previous week had the least stress, and their blood pressure returned to normal fastest after their test. Penetrative sex was farm more effective in this regard than masturbation or oral sex.
