Sex eases public speaking
According to a study by Stuart Brody, psychologist at University of Paisley, UK, penetrative sex can ease the stress of nervous public speakers. 24 women and 22 men were asked to keep a diary of their sexual activity for two weeks and then had to make a speech in public and perform mental arithmetic out loud. Those who had sex during the previous week had the least stress, as their blood presure returned to normal fastest. Oral sex and masturbation were much less effective. "The effects are not attributable to the short-term relief afforded by orgasm but, rather, endure for at least a week," says Brody, who thinks that sex releases a special pair-bonding hormone called oxytocin that produces the calming effect.
