"What about after marriage?"
Many married people then begin playing revolving beds. Many men and women who are used to multiple partners may not really settle down into a monogamous relationship.
I thought the title was about ten people (not the number of sex partners) out of a survey of however many were normal before marriage. Guess I need better reading glasses and should read the article and threads before I reply. Just making a joke that they may not remain normal after marriage. Ha Ha.
After reading the replies I've got to go with the professor (Economist_MA) as the most normal.
