The American Association of Sexuality Educators, Counselors and Therapists (AASECT) believes "sexual healing should be accessible to every individual interested in furthering their capacity for erotic pleasure as well as for gratifying emotional relationships, and that such services should be provided in a manner that secures the client's or patient's privacy, confidentiality, and self-respect."
Sex Therapy is a sexological method to treating sexual issues by completely talk therapy. There are no physical exams, no nudity and certainly no sexual touching. Sex therapy educate couples, helps them talk about sex with each other and address sexuality related issues, such as low sexual desire, erectile dysfunction, arousal disorders, delay or absence of orgasm, etc.
What I want to say about sex is, life is already serious enough, why not make sex to be delightful and enjoyable. Marilyn Monroe definitely would agree with me.
