In most cases, one of two things:
excitement or anxiety. For example, the first few times a young,
inexperienced man has sex with a partner, he has trouble controlling
the way he responds -- it feels involuntary, like being on autopilot.
Usually, practice makes perfect. He (and his partner) may also be
afraid that what they're doing is immoral, or worried they'll get
caught in the act, so the sex is often rushed and unsatisfying.
Climaxing quickly may begin during youth and then become an
unconscious, physically ingrained habit that persists later in life.
If the problem crops up during adult
years, it's probably due to anxiety (although the excitement factor
can return if, for example, you're having sex after a long time
without doing so). Any number of things can cause anxiety during
sex, including wanting to avoid pregnancy, stress at work or in
other areas of your life, and the fear that you may not be pleasing
your partner. Premature ejaculation is rarely caused by physical
disorders, but possible causes include multiple sclerosis, extreme
sensitivity in the penis, injury to the nerves, and other
neurological problems. |
