Rob Lowe: I struggled with monogamy

Rob Lowe admitted monogamy didn't come easy for him.

The "Parks and Recreation" actor told Haute Living LA that when he first met his wife, it was the first time he tried to be in a committed relationship.

"I had met my now wife, Sheryl, and was attempting my first try at monogamy, which was not really in my nature at the time, and I wasn't able to do it," Lowe told the mag.

The actor said he had to stop and "examine how I was living."

Lowe, who celebrated 24 years of sobriety earlier this year, quit drinking in 1990 and entered a rehabilitation clinic. He described his time in rehab as "one of the most exhilirating, liberating and exciting four weeks of my life" in his 2011 memior "Stories I Only Tell My Friends."
