This physician's guide offers parameters for discussion of sexual health issues. A sexual history needs to be taken during a patient’s initial visit, during routine preventive exams, and when physicians see signs of STDs. The dialogue lends itself to the opportunity for risk-reduction counseling and sharing information about behaviors that may place patient at risk of contracting STDs. A sexual history allows physicians to identify those individuals at risk for STDs, including HIV, and to identify appropriate anatomical sites for certain STD tests.
