The use of geolocation apps, and its link with physical, psychological, and social harms for the individual as well as society has been described \u2018Polydrug use\u2019\u2014combining multiple substances to amplify or diversify effects\u2014is frequently reported across these groups. This article provides a comprehensive overview of the sexual effects of substances commonly used in chemsex contexts. We introduce the Pharmacosex Wheel, a visual tool that categorizes drugs based on their pharmacological properties and their specific effects on sexual experience. Substances are grouped into seven classes: stimulants, empathogens, psychedelics, dissociatives, depressants, opioids, and cannabinoids. Each class is discussed in relation to its typical impact on sexual behavior, desire, sensation, and connection. To further illuminate the dynamics of polydrug use, we present a layered model that maps core and intersecting effects of combined substances. Core effects include stimulation (e.g., from stimulants), disinhibition (e.g., from depressants and dissociatives), and altered sensory perception (e.g., from empathogens, cannabinoids, and psychedelics). When substances with different core effects are combined, intersecting effects emerge\u2014such as euphoria, empathy, or chill\u2014which often result in rich and multifaceted sexual experiences. This model also incorporates user motivations, acknowledging that the choice of substances often aligns with specific desires or anticipated outcomes. Finally, we position the most commonly used substances within this framework, grouping them according to their chemical structure, pharmacological action, and the experiential reports of users. By approaching chemsex from a drug-positive perspective, without neglecting potential negative impacts, this article aims to foster a nuanced understanding of substance use in sexual contexts. Our goal is to support more informed research, destigmatize user experiences, and contribute to the development of tailored care within drug and sexual health services.<\/jats:p>","DOI":"10.3389\/fpubh.2025.1618070","type":"journal-article","created":{"date-parts":[[2025,7,10]],"date-time":"2025-07-10T05:31:06Z","timestamp":1752125466000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":12,"title":["Polydrug
