BEING IRRESISTIBLE

"One reason for this is that they think they have had an impact on you, which is very seductive.

"The other is based on a theory that the combination of stress with sudden relief causes significant emotional turmoil which is often mistaken for attraction. Indeed, your date gets quite stressed when you disagree with everything they say, but when you switch to being more agreeable the wave of relief they feel makes them more attracted to you."

Persaud adds that the later you make the switch, the more attractive your date will find you because the correlation between stress and relief is increased.

"Another good tip is to always tailor your seduction techniques to the person - nobody ever wants to hear a general chat-up line as it displays a remarkable lack of imagination or interest.

"Try to think of something that indicates a specific and deep interest, and make a concerted effort to notice something unusual about them," he advises.
