The Importance Of Breasts in A Sexual enviroment.

SEXUAL ROLE OF BREASTS

Breasts play an important part in human sexual behavior. They are one of most visible or obvious female secondary sex characteristics,[9]. Compared to other primates, human breasts are proportionately large throughout adult females' lives and may have evolved as a visual signal of sexual maturity and fertility.[10] On sexual arousal breast size increases, venous patterns across the breasts become more visible, and nipples harden. Breasts are sensitive to touch as they have many nerve endings, and it is common to press or massage breasts with hands during sexual intercourse. [11] Oral stimulation of nipples and breasts is also common. Some women can achieve breast orgasms. In the ancient Indian work the Kama Sutra, marking breasts with nails and biting with teeth are explained as erotic.[12]



BREAST ORGAMS




A breast orgasm is a female orgasm that is triggered from the stimulation of a woman's breast.[9] Not all women experience this effect when the breasts are stimulated; however, some women claim that the stimulation of the breast area during sexual intercourse and foreplay, or just the simple act of having their breasts fondled, has created mild to intense orgasms. According to one study that questioned 213 women, 29% of them had experienced a breast orgasm at one time or another,[10] This shows that it is not common, but it is possible. An orgasm is believed to occur in part because of the hormone oxytocin, which is produced in the body during sexual excitement and arousal. It has also been shown that oxytocin is produced when an individual's nipples are stimulated and become erect.[11]

Anal stimulation
Anal orgasm is an orgasm brought on by anal stimulation, such as from anal sex, an inserted finger, or a sex toy. Anecdotal evidence suggests that some women experience anal orgasm as qualitatively different from clitoral or "vaginal" orgasm, though for many others the distinction is less clear.[7]
In both sexes pleasure can be derived from the nerve endings around the anus and the anus itself. Hence, anal-oral contact can still be pleasurable without stimulation of the clitoris. Jack Morin has claimed that anal orgasm has nothing to do with the prostate orgasm, although the two are often confused.a>[8]
