Kera symptom: a method of treating erections used in Western Europe since the 18th and 19th centuries, in which a bread-like dough is passed through a cotton swab to the patient to first relax the buttocks and reduce tension in the abdominal muscles. As a result, an erection occurs at the point where the test touches the genital area. This psychologically makes it easier for the patient to communicate with the doctor, who is often an insecure patient. The essence of the method is to make yourself aware of the presence of an erection. The patient is offered to drink warm tea in sufficient quantities. He is stripped to the waist, lying on his back, his pelvis raised on a bolster. The doctor takes one end of the cotton wool in his hand, wets it in warm water, lowers part of the dough to the patient's penis, and the dough is rubbed from the frenulum to the scrotum. More often, two rollers are used: the first to the second alcohol on top, this allows you to speed up the processing process. Such touches help the uncontrolled erection to decrease gradually or stop completely, it stabilizes, and the possibility of premature ejaculation is significantly reduced.
