Women to the two vaginas sex porno

Science March 31, From ducks to dolphins, females have developed sex organs that help them deter undesirable suitors and derive pleasure from non-reproductive behavior. Rachel E. Patricia Brennan never intended to become a champion of the vagina. Her journey, in fact, began with a penis.

Back to Health A to Z. Labial fusion, or labial adhesion, is when the small inner lips around the entrance to the vagina become sealed together. In some cases, this can completely seal the vaginal opening, leaving a very small gap at the front that pee passes through. It's not certain what causes labial fusion, but it usually happens as a result of irritation or inflammation of the vaginal area, known as vaginitis. Without enough oestrogen in the body, which is quite normal before puberty, the lips can stay stuck together and gradually become firmly joined. The problem is rarely seen in girls after they begin puberty because this is when they start to produce the hormone oestrogen. For most babies or girls, labial fusion does not cause any problems and is often discovered accidentally by a parent or carer during nappy changing or bathing.

With a diet based on eucalyptus leaves that are very fibrous and low in nutrition and calories, koalas live a pretty lazy life, spending between 18 and 22 hours a day asleep. But does this lethargy also translate into the bedroom, or do koalas maintain an exciting sex life? Found throughout the eucalypt woodlands of Australia, koalas are quite solitary animals. Each individual sets up a home range, which can span a few acres to hundreds of acres. Though these home ranges can overlap a bit, the marsupials rarely run into each other.

Getting, and staying, pregnant could have been an impossible feat for Evelyn, a year-old Australian woman who has two vaginas and two uteruses — each of which leads to its own fallopian tube and ovary. For one, she can't precisely track ovulation since doctors don't know if both her ovaries release an egg each month or if they alternate. Plus, her extra reproductive tract means there's not a lot of room in her abdominal cavity for a fetus to grow. On top of that, her partner had a low sperm count. Doctors pushed the couple to use IVF and prepare for a very premature delivery.
