Omorashi: The act of holding ones own urine until the need to urinate is urgent, making another hold in their urine, or watching another person with an urgent need to urinate. This fetish sometimes originates from childhood memories of needing, or of seeing another needing, to urinate. Arousal may be triggered by seeing the body movements or facial expressions of that person. It can also be heightened by the person saying that they have to urinate. The arousal from being desperate comes from the sensation of having a full bladder. Voyeurism: Seeing another urinate without the persons knowledge either through video taping by a hidden camera, or by lurking in locations where people are urinating or are likely to have an urge to urinate.

Jennifer Eve Rehor of San Francisco State University points out that such data as exists on what she calls "unconventional" or "kink" sexual behavior is generally problematic because of the way that it has been collected, through criminal and clinical case studies. Behavior that appears neither in criminal trials nor in clinical studies (for example, because the individuals concerned do not commonly seek professional help) is therefore under-reported. Rehor therefore surveyed 1,764 female participants in "kink" behavior (mostly association with BDSM) in 2010–11, receiving 1,580 valid responses. What Rehor calls "urine play" is relatively infrequent, with only 36.52% of her sample reporting having done it or having had it done to them.
The University of Maryland Medical Center defines pathological gambling as "being unable to resist impulses to gamble, which can lead to severe personal or social consequences".Most other definitions of problem gambling can usually be simplified to any gambling that causes harm to the gambler or someone else in any way; however, these definitions are usually coupled with descriptions of the type of harm or the use of diagnostic criteria. The DSM-V has since reclassified pathological gambling as "gambling disorder" and has listed the disorder under substance-related and addictive disorders rather than impulse-control disorders. This is due to the symptomatology of the disorder resembling an addiction not dissimilar to that of a substance use disorder.
