How many times you should be having sex each week

The New York Post reports:

According to couples psychotherapist and certified sex therapist Sari Cooper, studies have found that “happy couples have sex three to four times per week.” But she cautions couples to be wary of the results, which may only survey snippets of respondents’ time together. “These polls may not take in the total picture of a couple’s life — think early marriage, pregnancy, having young children, or having a job that requires travel — and may cause perfectly happy couples to feel inferior or worried that they’re not doing enough.”

Counting.
