The Guardian has a good article out (here) introducing mindful sex by feature author Emine Saner. Pointing out the technique has been used for other issues, Saner reports on the prevalence of sexual problems before introducing mindfulness. She then introduces mindfulness, including a quick exercise to begin exploring mindfulness. Saner then talks about the use of mindfulness in addressing sexual dissatisfaction and problems quoting Brotto’s book Better Sex Through Mindfulness.
Overall Saner has written a quick introduction to mindfulness and sex. This could be a good article to have as an primer on the subject for clients.
