a
Adjusted odds ratio between race/ethnicity and semen exposure controlling for age, education, sexual orientation, partner relationship, and partner's perceived STI status.
b
The adjusted odds ratio for semen exposure (self) among men who assumed both receptive and insertive positions could not be calculated for this group due to the limited number of participants per cell.
