Understatement or new PC-term?

From The Metro:

GP told acne patient to perform sex act on him as 'cure'

A "narcissistic" GP who persuaded a teenage acne patient to perform a sex act on him at his surgery was struck off the medical register today.

Dr Ashenford struck up a friendship with the girl during appointments at the Sutton Hill Medical Practice in Telford, Shropshire, to treat her acne and a bad back. During one consultation in March 2007 he touched her breasts and remarked "that was nice". A week later he told her to remove her top and perform oral sex on him at the surgery, the General Medical Council hearing was told. He went on to buy her an iPod for her birthday and meet up in cafes where they "snogged and kissed".

Dr Steven Ashenford abused his position of trust to gain gratification in a "most reprehensible way" with the sexually naive 17-year-old girl, a disciplinary panel ruled.

I dunno. Is "sexually naive" the new PC-term for "mentally subnormal" or "a bit of a go-er" or something?

Did the doctor tell her that sperm is good against acne? BTW, I once had a girlfriend who was a nurse who told me that, so it is quite possibly true.
