Is there a connection between crossdressing and mdma?

There is no inherent or direct connection between crossdressing and MDMA, as they pertain to different aspects of human experience—crossdressing relates to gender expression and identity, while MDMA is a substance known for its psychoactive effects commonly associated with recreational use. However, in certain social settings, such as festivals or LGBTQ+ events, individuals may engage in both activities, leading to a perceived association. Ultimately, any connection would be context-dependent rather than a general rule.
