However, what I can say is that people have control at all times over what they will, and will not do. The only exception comes when individuals are under the influence of alcohol and other mild-altering drugs. While under the influence of alcohol, pot, cocaine etc., people tend to engage in activities that normally they would not. They tend to take chances more often, and are less likely to use condoms or use condoms correctly. My role here is to inform people about HIV and other STD's.
People can reduce their risk at ALL times.
High risk sex doesn't just happen. People allow it to happen. I know many, many people who don't engage in high risk activities, even when offered the opportunity. They have control over their own activities and lives. In regard to the question about testing positive.
