Scientific penis inside vagina

Just as women can have different sized breasts, hands, and feet, the size and depth of vaginas can also vary. According to one study, the average depth of a vagina is about 3. Other sources suggest that the average range of size may be about 3 to 7 inches approximately 7. In fact, the depth of the vagina from the opening to the tip of the cervix can measure anywhere up to 7 inches Several types of tissue line the inside of the vagina, including the mucosa. The mucosa is made up of specialized cells that secrete a lubricating fluid, which helps the vaginal walls to stretch. The exterior portion of the female genitals is the vulva.

EM participated in the execution of the study, particularly data collection and interpretation of the magnetic resonance findings. To find out whether taking images of the male and female genitals during coitus is feasible and to find out whether former and current ideas about the anatomy during sexual intercourse and during female sexual arousal are based on assumptions or on facts. Magnetic resonance imaging was used to study the female sexual response and the male and female genitals during coitus. Thirteen experiments were performed with eight couples and three single women. During female sexual arousal without intercourse the uterus was raised and the anterior vaginal wall lengthened. The size of the uterus did not increase during sexual arousal. Taking magnetic resonance images of the male and female genitals during coitus is feasible and contributes to understanding of anatomy.

A woman cannot get pregnant through penetration of the anus. However, make sure that semen does not enter the vagina. Some women want to have sexual intercourse during their menstrual period , others do not. A woman can have sexual intercourse during her menstrual period if she wants to.
