Marina Adshade considers a controversial fix to the high rate of sexually transmitted diseases among teenagers:
If in a sex scene (like a high school), there is only one girl who is willing to have sex for every 10 boys who are willing to have sex, then if one person in that scene contracts an STI, everyone else will become infected as well. This is because all the boys are having sex with the same few girls who are willing to be promiscuous. Increase the number of girls willing to having sex, however, and according to the theory the risk of contracting an STI decreases. This is because now each girl is now having sex with fewer men.
