An HIV-riddled Texas music teacher is up on sexual assault charges after cops say he was nabbed slithering out of the home of a 15-year-old boy. Cops say Roger (Joe) Kessler, 43, used popular gay dating app Grindr to meeting his young playmate. Kessler -- the maestro of man fun -- confessed to having sex with his teen temptress four times -- included at least one bareback romp sans protection. The teen's mom blew the whistle on Kessler, believing him to be a burglar -- instead of a buggerer.
The music man was busted and is being held on a $25,000 bond.
Investigators say that the 14-year teacher at Richardson ISD Academy is on leave. The boy was not a student and Kessler did NOT tell him he was HIV positive.
