This booklet series has been developed by specialist psychologists and medical doctors working in CNWL’s Sexual Problems Assessment and Treatment Service (SPATS). The information and exercises described in this booklet are based on psychological and sex therapy techniques that have been shown to improve sexual difficulties.

This series has been written for people of all genders, sexualities, sexual orientations, cultures, backgrounds and relationship statuses. While the suggestions and exercises in each booklet are based on principles that are relevant for everyone, some sections contain information about the biological and physical changes that can happen in specific parts of sexual anatomy. Some content and diagrams may not be reflective of your anatomy, including people who are intersex, people who have had gender affirming surgery, or people who have experienced physical changes due to specific medical conditions and/or treatment required.  In these instances, if further information is required we recommend you speak to your GP or a specialist in sexual medicine. All bodies are different and we invite you to use the booklets in the way they are most applicable to you.
