It’s ejaculation before beginning of sexual intercourse or on a first minute of it (usually after 10-20 frictions) which usually doesn’t give a chance to satisfy a sexual partner. Such short coitus from the beginning of sexual life often is a sign of paracentral lobules’ syndrome and needs to be treated with a help of sexologist.
It’s a relatively early ejaculation, if sexual intercourse lasts more than 1 minute, but in most cases this time is still not enough to satisfy a sexual partner.
Approximately 15-20% of men in one or another level have problems with control of ejaculation. Causes of premature ejaculation are low frequency of sexual intercourses (masturbation) which brings to exceeding sexual excitement; strong sexual constitution; feelings of fear and anxiety during intercourse which are connected to outer factors or worries about possible failure in satisfying of partner; being used to quick ejaculation which usually is observed for young men who have unfavorable environment for intercourses or have seldom intercourses with hipo-sexual partner which wants the intercourse to be over sooner; inflammatory illnesses of prostate, back part of the urethra and consequences of them; neurotic reaction and neurosis as well as syndrome of paracentral lobules.
With this form of sexual disorder it’s recommended to practice more of repeated intercourses, masturbate prior to it, during intercourse move attention from sexual irritators to something, non sexual, stop frictions once in a while or limit their amplitude, use condom and special lubricants which decrease sensitivity of receptors on the head of the penis (Novocain, etc., 10-30 minutes prior to intercourse).
There are developed special methods of training about how to move away ejaculation (therapeutic program of Masters & Johnson, Psychotherapy).
It’s discovered that one of the anti-depressant groups, particularly – Selective Serotonin Reuptake Inhibitors (SSRI) are having by-effects expressing as ejaculation delay, they include such medications as Prozac, Zoloft, Paxil, etc.
