Do you know how much sex you should be having?

Sexologist Jessica O’Reilly talks about old and new sex stats.

For a happy marriage, have sex three times per week! Is this theory Old or new?
New: once per week. Sexual frequency is positively correlated with well-being and relationship satisfaction, but the relationship is curvilinear with  sex no longer being associated with well-being at a frequency of more than once a week.

Everyone should do their kegels to stay healthy down there! Is this idea old or new?
New: It’s not as simple as a one-size fits all approach. Kegels are good for some people, but others (like me) who hold a good deal of tension in their pelvic floor need to be doing other things like stretches and squats. The best solution is to see your pelvic floor therapist.

Talking/teaching about sex encourages teens to have sex. Do you think this is a new or old theory?
New: Talking about sex doesn’t lead to sex. A rich body of research confirms that comprehensive education in sexual health do NOT hasten the onset of sexual activity and in fact, encourage healthy behavioural outcomes. 

Opposites attract, so find a partner who is your opposite in order to last. Is an old theory or new theory?
New: Balance theory -The consistency motive is the urge to maintain one's values and beliefs over time.
A study of 1500 pairs (partners and friends) found that we’re most attracted to those with whom we share similar values, prejudices, attitudes and personality traits. Another study of 174 couples found that those who are happiest are those with similar personalities. You may be attracted to an opposite at first, but the key to a long-lasting relationship is similarity. 

Communication is the key to a happy relationship. Is this theory old or new?
New: Accept that you can’t resolve every conflict. Dr. John Gottman’s research with couples in his love lab revealed that the happiest couples accept that not every issue is resolvable. Over 75% of couples rate relationships as “very happy” despite frequent arguing; 69% of conflicts cannot be resolved.
