to being a "denied orgasm" (which can sometimes lead to "blue balls" for both men and women). Alternatively (for men), the release of semen during the emission phase of ejaculation might be prevented by some sort of constriction ("blocked orgasm"). Depending on the relationship, subjects might be repeatedly teased to the point of orgasm several times, but without actual orgasm, causing feelings of intense arousal and psychological need. Total denial The practice of total sexual denial usually includes total avoidance of genital stimulation to the penis or vulva. This often involves the use of a physical barrier or device, such as a chastity belt or cage. Chastity belts or similar locking devices are available for all genders. Depending on the situation, sexual arousal may still be possible regardless of physical barriers to genital stimulation. This, however, depends on the belt used. Male strap-on harness A strap-on dildo may be worn by a male to still allow penetrative vaginal sex to the female while denying the male partner the ability to orgasm, and the male then may also wear a chastity device. This is distinct from pegging, as the strap-on in this case replaces the penis of the male. This can be seen as a form of total denial if the strap-on replaces the penis throughout the whole duration of the play, or as a form of teasing if the strap-on is only used during foreplay. In the last case, the strap-on can be used to prolong penetrative sex and thus sexually satisfy the female partner in case the male suffers from premature ejaculation. As a form of control Erotic sexual denial is sometimes used by a dominant to increase their control over a submissive. Because the submissive is kept in a state of sexual need and vulnerability, they are more likely to take a compliant stance with the dominant; failure to comply can result in additional teasing or an extended period of denial, among other punishments. Orgasm denial practices can allow the dominant to exercise control over many aspects of the submissive's life. As such, they are often (though not always) practiced as an extension or enhancement of a broader BDSM relationship, or as a means of establishing one. They can allow the dominant to experience enjoyable and sometimes intensely craved feelings of sexual control and erotic power, and the submissive can enjoy intense feelings of sexual objectification and submission
