This clinic specializes in treating premature ejaculation patients who ejaculate unintentionally. The clinic inserts the male organ directly into the nurse's vagina and has the patient hold back from ejaculating for as long as possible to improve premature ejaculation. If the patient ejaculates inside the vagina, the clinic will immediately insert the penis a second time to allow the patient to get used to the sensation of the vagina for as long as possible. Please watch the two consecutive ejaculations.
