I don't need a judge telling me that my daughters can or cannot have sex.
Just to fit some activist judges adgenda
Probation is purely a privilege. If she doesn't want to fulfil the conditions of probation, she can serve her sentence in confinement. If her parents don't "need a judge telling me that my daughters can or cannot have sex," they can come visit her in the lockup. Better yet, she could consider not committing the crime in the first place, and her parents could consider finding her a new school/new set of friends.
Trial courts are given a great deal of latitude in imposing conditions of probation. If any logical connection can be shown between the condition and preventing a re-offense, then it is permitted.
This is really along the lines of your standard probation condition requiring the criminal to avoid bad company, especially other criminals. Since she was sentenced for a drug offense, it can be argued that this is logically related to discourage trading sex for drugs and reduce the incentive for her to hang with her druggy friends.
Well once your daughters are convicted of a crime, it really isn't up to you what sentence the Judge hands down.
