Because stopping the study would stop the control group from having risky sex in the future... Both groups will continue to have sex. They will both be exposed. And if you have played roulette, there can be streaks, but in the end everything will get closer to even.
And it seems unfair to have one group of people not having sex because they are healing and hyper-sensitive for a few weeks of the short study time. And who knows what the personalities of the people in each group was or how often they were having sex with new partners (or condom use). That is a big assumption they made right there.
