Based on the premises that the dominant analytical orientation of research on mobility–related sexuality isgrossly inadequate and the incessant calls for innovative and responsive research and methodological design toaddress the issue, this paper explores certain gaps in the risk-sexuality inclinations of a Lagos-based group ofcirculatory traders. Employing relevant circulatory-cum- sexuality data of the study group, acquired by acombination of purposive and stratified random sampling designs, the paper employed a set-theoretic approachto the study population along a novel ‘origin-destination’ by ‘risky-cum-riskless’ sexuality profile.The study compared the levels and dynamics in the committal of three specific risk-sexuality variables. It wentfurther to examine how the study population is structured in the context of the devised ‘origin-destination’ by‘risk-riskless-sexuality’ grouping. Further, it also examined how the pattern differentiated the categorizedregional destinations, in terms of the risk-designation status of their visitors. The study among others discoveredthe tendency for greater intensity of risky-sexuality locally than at external destinations; a modal percentage of‘origin-destination’ riskless group, but characterised by the least mobility rate, and also a small size ‘origindestination’risky subgroup, but which has the greatest spatial mobility rate. The paper finally explores theresearch and intervention clues of its findings.Keywords: Sexuality-Risk, mobile population, disaggregated analysis, intervention
