New York: Premature ejaculation including female sexual dysfunction should not be classified as an illness, argue researchers, adding that the illness factor may have been constructed by sexual medicine experts under the influence of drug companies.

“It is important for men to understand that in premature ejaculation, the physiology of ejaculation and orgasm is not impaired, and that it is normal in adolescent males especially during their first sexual encounters," explained Dr Vincenzo Puppo, co-author of a paper appeared in the journal Clinical Anatomy.
