ahuya kantam nava-sangama-hriya
visankitam kankana-bhusite kare
pragrhya sayyam adhivesya ramaya
Calling forward His beloved, who was anxious and shy at the prospect of this new contact, the Lord pulled her by her bangled hands onto the bed. Thus He enjoyed with that beautiful girl, whose only trace of piety was her having offered ointment to the Lord.
Srila Visvanatha Cakravarti explains that the words nava-sangama-hriya indicate that Trivakra was in fact a virgin girl at this point. She had been a deformed hunchback, and the Lord had recently transformed her into a beautiful girl. Therefore, although clearly lusting after Sri Krsna, she was naturally shy and anxious.
