Researchers in the Department of Psychology at McGill University, Canada are looking for folks to participate in an online survey exploring male body image and sexuality.
From the survey page:
The purpose of this study is to better understand how men evaluate certain features of their genitals, and the factors that influence this perception. It is hoped that better understanding of male genital image concerns and the factors involved may improve body image treatment in the future.
To sweeten the deal, if you want to give them your contact info, participants can enter a contest for one of three $100 amazon.com gift cards. But you don’t have to enter the contest or give any identifying info to take the survey.
