This study examines the relationship between sexual position discordance, sexualized substance use, and sexual satisfaction among nearly 2,000 sexual minority men in Canada. While discordance between preferences and behaviors was common and not linked to lower satisfaction, frequent use of substances such as crystal meth and poppers was associated with reduced sexual satisfaction.

This research develops a new way to measure mathematical language by integrating words, symbols, and graphs. Through experimental tasks, it shows that these skills predict mathematical performance. The findings highlight the importance of teaching connections between representations, with implications for improving mathematics education and understanding how language shapes learning.
