Dr. Leanna Wolfe presented findings from an internet survey on sexual and relationship happiness conducted between August 2010 and May 2011, which gathered data from 6,970 respondents. The survey revealed that a significant portion of participants reported dissatisfaction in their current relationships, with 50.4% expressing unhappiness and 61.2% having one or more outside lovers. Additionally, the study noted a rise in heterosexual anal play, particularly among those under 44 years old, with various motivations for this behavior.
