Mare Simone, 54, from Chelsea, West London, has devoted her working life to helping men, women and couples overcome problems in the bedroom, and as a qualified sex therapist, she has given lessons to more than 10,000 clients over the past 23 years.
Simone estimates that she has had penetrative sex with 1,500 of them, and insists there is nothing illegal about what she does.
"I earn my living by sleeping with other women's husbands or boyfriends. But I am in no way a prostitute as sex surrogacy is legal, as long as it is done in a therapeutic and healing atmosphere," the Sun quoted her as saying.
"People are paying for counselling and to cure their problems - not sex.
"I am helping improve and change the sex lives of thousands of men, which means I am also helping improve the sex lives of their wives and girlfriends.
"Some women become baby surrogates because they want to help women who can't have children. In the same way, I feel drawn to helping others have an intimate sex life.
"My job is so fulfilling and enjoyable. Seeing my customers leave with a newfound sexual confidence is a wonderful sight.
"Since I started surrogacy work, I have seen more than 10,000 clients and estimate that I have had penetrative sex with around 1,500 men. I continue to see clients weekly.
"Witnessing the men and women I help make huge improvements and feel confident about their bodies is wonderful.
"In the 20 years I have been doing this job, I have never felt miserable about going to work. I love what I do and have no plans to retire within the next ten years.
"I am a sexual healer and so proud and happy that I found my dream job," she added.
