There is a positive correlation (P<0.05) between history of abuse by family members and the number of risky sexual behaviors. There is no significant correlation between marital status, educational status, and parent's living status with risky sexual behaviors (P>0.05).

Methamphetamine consumers use can have more efficient practices, be hyperactive, and take sexual risk-taking behaviors. These behaviors are particularly remarkable in homosexuals. The present study was conducted based on casual-comparative method in the field of descriptive studies. Since 1 March to 25 June 2015, a total of 62 MSM subjects were selected based on chain method and divided into two groups of methamphetamine dependent (n=30) and non-dependent ones (n=32). sexual behaviors were examined by sexual behavior questionnaire based on 3 dimensions of sexual thoughts, sexual pleasure, and sexual hyperactivity. High-risk sexual behavior were evaluated by sexual behavior questionnaire, their relation with participants’ educational status, occupation, age, income, and number of sexual partners in the last 3 months were analyzed using the parametric T-test. Data analysis showed that methamphetamine dependent MSM were significantly higher (P<0.01) in all 3 components of sexual thoughts and pleasure, hyperactivity, and sexual behavior compared to non-dependent group. However, regarding age, there was no significant difference between age and sexual risk behavior (P=0.05). methamphetamine dependent MSM have a unique experience of thoughts, pleasure, and aspirations and have high tendency to high-risk sexual behavior. These findings are consistent with the previous research on the importance of stimulant consumption and specifically methamphetamine in creating high-risk sexual behavior. Controlling methamphetamine use plays an important role in preventing the transmission of infectious diseases.

The structural and cultural developments in modern societies have increased the scale of individual's sexual satisfaction and brought problems to the function of the family in regulating sexual behavior. The main question that arises here is: how can men and women respond to their sexual needs within the family framework under these conditions? What are the indicators of the function of regulating the sexual behavior in an ideal Muslims family? Regulating sexual behavior cannot be attained through a complex mental and emotional process.
