Is a probation condition of probation valid if it prohibits a defendant from engaging in sexual acts while on probation that is not in itself criminal?

The discretion granted to the courts to impose probation conditions is not unlimited. "A condition of probation which (1) has no relationship to the crime of which the offender was convicted, (2) relates to conduct which is not in itself criminal, and (3) requires or forbids conduct which is not reasonably related to future criminality does not serve the statutory ends of probation and is invalid." (People v. Dominguez (1967) 256 Cal.App.2d 623, 627.) "Conversely, a condition of probation which requires or forbids conduct which is not itself criminal is valid if that conduct is reasonably related to the crime of which the defendant was convicted or to future criminality." (People v. Lent (1975) 15 Cal.3d 481, 486.)
