Princess and the Pee

Prince meets the love of his life, a true Princes, but she is down on her luck. The Prince is smitten and proposes marriage, but his mother (always the mother-in-law) is less sanguine about the gal’s qualities and requires a test – the Princess must sleep on twenty mattresses under which a pea will be placed. If the Princess feels the pea during the night, then the Prince’s mother will acknowledge her royal bearings. Unbeknown to all, the Princess suffers from bladder incontinence due to an athletic injury; nerve supply to her pubococcygeus muscles was injured. During the night, the Princess does experience incontinence and wets all 20 mattresses (there had been lots of drinking at the palace that night) – the wedding is called off by the mother-in-law.

Question: Which of the indicated muscles represents the pubococcygeus? 

Postscript: If you were the Prince, what would you do?
