Stimulation of Nipples

Stimulation of nipples is a common human sexual practice, either for itself or as part of other sexual activities. The practice may be performed upon – or by – people of any gender or sexual orientation, but is more commonly performed on women. Breast and nipple stimulation of women are a near-universal aspect of human sexual activity, but stimulation of nipples of males are not as common.

The male or female breast, nipple and areola develop similarly in the fetus and during infancy. At puberty the male's breasts remain rudimentary but the female's develop further, mainly due to the presence of oestrogen and progesterone, and become more sensitive. All breasts have the same number of nerve endings no matter how large they are. Accordingly, smaller breasts are more sensitive while larger breasts can be stimulated more forcefully.

The touching by one person of the breasts and nipples of another is normally an indicator of intimacy, and allowing breasts to be touched is an indication of either trust or, if unwelcome, of submission. The touching of the nipples can be a form of foreplay giving raise to sexual arousal and an erection of the nipples. Breasts, and especially the nipples, are highly erogenous zones, for both men and women, and have a heightened sensitivity, the stimulation of which may result in the production of erotic sensations or sexual excitement. A person may experience a spontaneous erection of the nipples, with all the associated physiological changes, as a result of sexual arousal or as a reaction to cold.

Nipples can be stimulated orally, digitally, manually or by the use of an object. Oral nipple stimulation would involve a sex partner stimulating a person's nipples by licking, sucking, biting or blowing on the partner's nipples. Other ways of stimulating nipples include fondling or rubbing them with the hands or by using a soft object. Some people self-stimulate their nipple.

Stimulation of a woman's nipples promotes the production of oxytocin and prolactin, and can create physiological changes to her genitals. Oxytocin creates maternal feelings in a woman and is known to decrease anxiety, and to increase pair bonding and increase trust.  The release of oxytocin can result in sexual arousal of the person and the erection of the nipples, both of which make the nipples even more sensitive to touch.

Prolactin produces sexual gratification after a sexual activity. Some women report achieving orgasm without other forms of sexual stimulation.

Breast orgasm is also believed to be due to oxytocin. However, a 2011 study using magnetic resonance.

Erectile Dysfunction is ED

ED is the inability to get or keep an erection firm enough for sexual intercourse. ED can be a total inability to achieve an erection, an inconsistent ability to do so, or a tendency to sustain only brief erections.

ED is sometimes called impotence, but that word is being used less often so that it will not be confused with other, nonmedical meanings of the term.

The National Institutes of Health estimates that ED affects as many as 30 million men in the United States. Incidence increases with age: About 4 percent of men in their 50s and nearly 17 percent of men in their 60s experience a total inability to achieve an erection. The incidence jumps to 47 percent for men older than 75.> But ED is not an inevitable part of aging. ED is treatable at any age.

Audition sides

Occasionally audition sides are made available to actors days before an audition. When any actor has the advantage of getting audition sides in advance, it is always wise to study them; going into an audition prepared can make a big difference in the quality of an audition. Audition sides are one of many tools available to actors. To learn more about sides and how to get the most out of them for auditions, go to audition sides. Auditions sides are designated pages of text from a play or scene/s that actors are given to perform at an audition.

The process of auditioning for a role in a performance, as in a demonstration of acting, dancing, singing ability. Auditions are used in the casting process to demonstrate the level and range of a performer's talent, and functions as a job interview for the performing arts. For actors, the audition piece is typically not from the show being considered. Some auditions involve cold reading, or performing a script that the actor is not familiar with. Likewise, musicians may be asked to sight-read music at various levels of difficulty. This is similar to many dance auditions, rather than showcasing prepared work. To learn more information about the audition process, go to auditions.

Erectile Dysfunction

Erectile dysfunction is sexual dysfunction characterized by the inability to develop or maintain an erection of the penis during sexual performance. A penile erection is the hydraulic effect of blood entering and being retained in sponge-like bodies within the penis. The process is often initiated as a result of sexual arousal, when signals are transmitted from the brain to nerves in the penis. Erectile dysfunction is indicated when an erection is difficult to produce. There are various circulatory causes, including alteration of the voltage-gated potassium channel, as in arsenic poisoning from drinking water. The most important organic causes are cardiovascular disease and diabetes, neurological problems (for example, trauma from prostatectomy surgery), hormonal insufficiencies (hypogonadism) and drug side effects.

Psychological impotence is where erection or penetration fails due to thoughts or feelings (psychological reasons) rather than physical impossibility; this is somewhat less frequent but often can be helped. Notably in psychological impotence, there is a strong response to placebo treatment. Erectile dysfunction, tied closely as it is about ideas of physical well being, can have severe psychological consequences. Besides treating the underlying causes such as potassium deficiency or arsenic contamination of drinking water, the first line treatment of erectile dysfunction consists of a trial of PDE5 inhibitor drugs (the first of which was sildenafil or Viagra). In some cases, treatment can involve prostaglandin tablets in the urethra, injections into the penis, a penile prosthesis, a penis pump or vascular reconstructive surgery. The Latin term impotentia coeundi describes simple inability to insert the penis into the vagina. It is now mostly replaced by more precise terms. The study of erectile dysfunction within medicine is covered by andrology, a sub-field within urology.
