Exhibitionism: Becoming noticeably desperate or wetting oneself with the express purpose of being seen by strangers. In a few relationships, it leads as far as total submission of one partner in the truest sense of the phrase total power exchange . Reading or viewing hot gay sex pornography, sexual fantasy or other erotic lesbian milfs stimuli may lead to a desire for sexual release such as by masturbation.

The slave is usually strictly forbidden from placing their lips directly on the body of the dominant so the practice routinely involves them receiving much of the spray all over their face, hair and body, however, another way of doing this that applies mostly to male dominants, is to place the mouth on the head of the penis and drink the urine as it is released. In these research publications, it is suggested that real female ejaculation is the release of a very scanty, thick, and whitish fluid from the female prostate, while the squirting or gushing shown frequently in pornography is a different phenomenon, the expulsion of clear and abundant fluid, which has been shown to be a diluted fluid from the urinary bladder. However, gay pornography in the modern world is mostly concentrated in the making of home videos , cable broadcast and emerging video on demand and wireless markets, as well as images and movies for viewing on the Internet. It is a matter of subjective definition whether participation of a third person without physical contact constitutes a threesome. To avoid soreness from this resulting friction, some may prefer to use a personal lubricant, masturbation cream or saliva hentai sex during masturbation. The consensual submission of the submissive is sometimes demonstrated to others by symbols indicating his/her belonging to the dominant, such as wearing a collar, special tattoos, piercings, a very short haircut or a bald head.
