P-02-75 EFFECTS ON SEXUAL RESPONSE AND MOTIVATIONS IN ENGAGING IN CHEMSEX ACTIVITIES IN A GROUP OF MEN WHO HAVE SEX WITH MEN (MSM)

Objectives: Chemsex is referred to illicit drugs use (GHB/GBL, methamphetamine, and mephedrone) to enhance the sexual activity in Men who have Sex with Men (MSM). Most studies focused on the health risks associated to chemsex, while less attention was paid on the effects on sexual response and motivations to engage in this behavior. The current study aims to investigate how drugs used in chemsex might affect the sexual activity and which are the motivations encouraging men to use them. Methods: 20 MSM involved in chemsex activities (mean age ¼ 38.6±12.4) were assessed with an ad hoc semi-structured interview between February and July 2019 exploring sexuality in chemsex. Interviews transcripts were thematically analyzed. Inclusion criteria were being cisgender MSM and having at least a chemsex experience in the last year. Results: Participants showed significant individual differences in the effects of chemsex drugs on sexuality. The most common effects were an increase in sexual desire and subjective arousal, usually associated with a higher disinhibition and the presence of erectile difficulties. Some men reported a significant extension of the sexual experience (till 24-48 hours), with consequent delais and difficulties in reaching orgasms. Many participants highlighted an intensified perception of intimacy during chemsex. Regarding feelings and motivations, the increase in arousal and pleasure are the most frequent factors reported, followed by the possibility to lose controls and being considered as part of an intimate group/community. Some men reported to be motivated by their partners and friends and to use chemsex drugs as palliative for negative mental states and sexual/ identity problems. Conclusions: Effects on sexuality and motivations for engaging in chemsex are peculiar factors to better understand this complex and multifactorial phenomena. Despite the methodological limitations, results highlighted some key factors that should be considered for harm reduction-based programs and integrated treatment for problematic chemsex.
