Today's enlisted people know in advance what will be required, including vaccinations. If birth control is mandatory, a female enlistee would give informed consent to medication at enlistment. Disobedience at a later date is a different matter.
BTW, why the assumption that enlisted people, male or female, lack sexual self control? Many people are perfectly able to control themselves, particularly if they are married. Why force those individuals to take drugs they do not need?
I didn't say ALL of them are having sex.
But a lot of them DO. And it's not just the enlisted . The Occifers do it , too.
It's a problem.
