A previous career in gay porn has put the brakes on a teaching career for Shawn Loftis, who went by the screen name Collin O'Neal.

According to alternative weekly Miami New Times, Loftis built a gay porn empire that included his own production studio, Collin O'Neal Productions, and multiple awards for showing off his talents in films such as Mo' Bubble Butt, Humping Iron and Desperate Husbands.

Last year, however, Loftis turned his back on gay porn, selling off his production company to pursue a teaching career.

Loftis, who earned a master's degree in public administration from the University of Miami, began substitute teaching in public schools throughout the Miami-Dade system.

He was suspended in January after a school principal was tipped on his former career.

Loftis was accused of breaking a school district rule which demands that school faculty “conduct themselves, both in their employment and in the community, in a manner that will reflect credit upon themselves and the school system.”

In April, the Florida Department of Education revoked his teaching certification.

He told the paper that he believes his porn career wouldn't have mattered much if he had done straight films.

Loftis has since returned to the world of gay porn.
