Menstruation | yngvethoresen.com

See Article History Menstruation, periodic discharge from the vagina of blood, secretions, and disintegrating mucous membrane that had lined the uterus. The biological significance of the process in humans can best be explained by reference to the reproductive function in other mammals. In a number of species of wild sheep, for example, there is only one breeding season in the year; during this season a cycle of changes takes place in the reproductive organs, characterized by ripening and release of ova from the ovaries, increased blood supply to the genital tract, growth of the uterus, and proliferation of its lining. There is a discharge of blood and mucus from the uterus and vagina, and this is the time when coition may take place.

Menstruation

Describes someone who does not engage in sexual activity, usually by choice. Diaphragms, cervical caps and contraceptive sponges are kinds of cervical barriers. This is often used by people who are trying to get pregnant but is NOT an effective birth control method, as it fails frequently due to fluctuations in a woman's cycle and the fact that sperm can live in a woman's reproductive tract for several days.

Больше крупных планов с камшотами. Как на той фото со спермой на лице. Больше красивых окончаний. И анала побольше в разных позах. С пробкой может поиграй или камушком каким. Крупные планы разработки ануса.
