The prevalence of sexual dysfunctions can easily be ascertained by conducting a survey of sex therapists. 通过性治疗师所进行的调查，性功能障碍的流行状况可以容易地被查明。
It may be an oversimplification to speak of a sexual dysfunction in any individual, because, as a rule, it manifests itself only in relation to another person. 要给任何一个个体诊断成性功能障碍可能是过于简单化了，因为，通常的情形是，性功能只在涉及到另一个人时才会显现。
