""Coitus reservatus (coitus, "sexual intercourse, union" + reservatus, "reserved, saved"), also known as sexual continence, is commonly thought of as a form of sexual intercourse in which the penetrative partner does not attempt to ejaculate within the receptive partner, but instead attempts to remain at the plateau phase of intercourse for as long as possible avoiding the seminal emission. Another term used for this kind of relationship is the word karezza.
According to its creator, Alice Stockham, the word karezza is derived from the Italian word "carezza" meaning "caress". However, Alan Watts believed, in error, that it was a Persian word.The concept of karezza is loosely akin to maithuna in Hindu Tantra and Sahaja in Hindu Yoga.
The Rosicrucians have used "coitus reservatus" or "karezza" as an esoteric practice.[citation needed]
Control of ejaculation is a key aspect of Taoist sexual practices (known as "cai Yin pu Yang" and "cai Yang pu Yin") (Wikipedia)
