Aim of the study:
The primary function of temperament is to adapt the strength and frequency of stimulation to the individual's processing capacity. The purpose of this study was to determine the differences in temperamental traits in men with risky sexual behavior (RSB) and compulsive sexual behavior disorder (CSBD).

Subject or material and methods:
Data were collected from December 2019 to January 2021. The analysis included 425 men: 63 with RSB (M=35.70 years), 98 with CSBD (M=37.99 years), and 264 in the control group - CG (M=35.08 years). The following methods were applied: Temperament Inventory, Sexual Addiction Screening Test, Risky Sexual Behavior Scale, and self-report survey.

Results:
Higher intensity of emotional reactivity (p<0.001), sensory sensitivity (p=0.034), and a lower intensity of endurance (p=0.032) and briskness (p<0.001) were found in the CSBD group compared to the CG. In the CSBD group, the intensity of emotional reactivity was higher (p<0.001), the intensity of briskness (p<0.001), and activity (p=0.017) were lower compared to RSB group. No differences were found between the RSB group and the CG.

Discussion:
Effective self-regulation results from a specific temperament profile which is the relationship between individual temperament characteristics, with primary emphasis on the relationships between the intensity of behavioral energy levels, including endurance, emotional reactivity, and activity.

Conclusions:
Patients with CSBD show a lower need for stimulation and a greater tendency to avoid it, compared to men with and without RSB. The men with RSB need to consider the current pleasures of life more than the other groups studied, but their temperamental structure is similar to those without RSB.
