Mostly, the sex surrogate is involved in teaching non-sexual touch and intimacy techniques as well as education about sexuality, body image, assertiveness and communication skills building for a romantic or sexual context. Sex surrogacy has shown great success when used as part of a treatment plan for single men suffering from erection and ejaculation issues, and single women who suffer from painful intercourse. A sex surrogate is an individual who is specifically trained in working with individuals on addressing physical and emotional barriers to intimacy, including sexual intimacy. Usually, accredited sex surrogates are university graduates in psychology or some form of physical science degree, who have seen and understood the importance of intimate relationships in overall wellbeing.
