The Internal Sex Organs

The Vagina

The vagina during sexual intercourse
The vagina adjusts to the size of any inserted penis, large or small. However, that portion of the vagina which lies closest to the external opening may, in some cases, become too relaxed for the preference of either sexual partner. This can happen after childbirth, for instance, or simply as a result of the aging process. Conversely, it is also possible for the vaginal entry to become so tense and tight that it cannot be penetrated. Such a vaginal spasm is called vaginismus. Both problems can usually be solved by behavior therapy and/or appropriate exercises. Some of these exercises, the socalled Kegel exercises (named after the 20th century American gynecologist Arnold Kegel), can easily be performed by all women at all times, anywhere.
