A 2011 study conducted by the crew at the Social Indicators Research Journal
revealed that the link between sexual fulfillment and happiness is indeed a strong one; regardless of race, creed, religion, martial status or income. It was shown that people who had sex at least two or three times per month were 33% more likely to report a greater level of happiness in their lives than those who have been without sex for a year or more. Participants who volunteered that they have sex somewhere between two to three times each week indicated an even higher degree of joy and contentment.
