Updated Sept. 7: Revised to include sentence.

An Arlington man who was looking for "a family with a kinky side" has been sentenced to 15 years in federal prison for trying to entice a minor for sex.

Marquis Konrad Streaty, 32, was found guilty in May of one count of enticement of a child.

"Anyone who attempts to entice a child to engage in sexual activity commits a serious crime and will face serious consequences," U.S. Attorney John R. Parker said in a statement. "That's the law and this office will enforce it."

According to a criminal complaint, a Homeland Security agent found an ad online on March 2 with the title "Family Nudism?? Or more?? — m4mw."

"I'm looking for the Husband/Wife type of nudism by itself but also the kind that goes deeper than that — from the whole family nudism that includes sons and daughters as well or maybe it's just Mother/daughter, Dad/Daughter, Aunt/Niece, Uncle/Niece, Grandmother/Granddaughter, etc.," the ad read.

The poster described himself as a "VERY, VERY discreet" man who was "just looking for a family with a kinky side."

An undercover agent then responded to the ad, pretending to be a man with a 13-year-old stepdaughter "who likes to play and might be up for a new friend."

The man replied, "I am interested in meeting her and you," and made plans to meet at a hotel. He later gave a phone number that authorities connected to Streaty.

The agent gave Streaty a phone number that purportedly belonged to the girl; he sent a nude picture and discussed sex acts, the complaint says. When told again that the girl was 13, he replied: "I know It's cool."

On March 9, Homeland Security agents met Streaty at a hotel in Fort Worth.

After he was arrested, Streaty told the agents that he traveled to the hotel only to tell the girl's stepfather that he wouldn't have sex with a minor.
