Planned Parenthood is currently being damned for giving girls who claim to be under the age of consent information about birth control. Legally, they are probably required to do so, regardless of the fact they are there with someone who may be their pimp. (And let’s be honest, real pimps don’t identify themselves to PP counselors.)
In Washington, the age of consent is 16. Privacy rights regarding sexual health begin at 14. Providers can’t refuse care based on age; they are ethically required to give the care and legally required not to disclose it (unless there’s actual evidence of abuse).
