Cauthen claimed in her suit that she complained about Primo's behavior to Spurs officials, but said they turned a blind eye to it and refused to punish the 19-year-old because he was an up-and-coming player with big potential.
She sued for unspecified damages.
For Primo's part, his attorney William J. Briggs II, said in a statement shortly after the lawsuit's filing that the basketball player never intentionally exposed himself to Cauthen. He called her allegations "either a complete fabrication, a gross embellishment or utter fantasy."
Primo was waived by the Spurs on Oct. 28. He's yet to sign on with a new team.
