Through physical encounters, sex surrogates can help patients build sexual skills, a healthy body image and an improved comfort level with intimacy. Continued treatment with a sex surrogate can also help patients learn to develop healthy ongoing relationships and proper social skills.

Sex surrogates don't just provide sex. According to a 1983 study of surrogates by Dr. Raymond J. Noonan, 48% of a surrogate's time is spent on non-sexual exercises and experiences.

The study also showed that surrogates spent 34% of the time talking with their patients and another 4.5% teaching them social skills, often in public settings. Only 13% of a surrogate's time goes toward sexual encounters, according to the study, and most of these are toward the end of the patient's treatment program.

In addition to helping patients cope with definitively sexual problems, sex surrogates often work with patients on their communication skills, emotional attachment issues and even their hygiene, with the ultimate goal of helping the patient become a more sexually and socially healthy person.

According to sex surrogate Lisa Carr on CarnalNation.com, surrogacy "aims to enrich the client's world sensually and emotionally as well as erotically."
