You may want to think twice before sending a photo of your privates to Debra Messing.

The “Mysteries of Laura” star publicly shamed an overzealous male admirer, who had passed along a snap of his penis via Twitter.

“Sending pix like this is NEVER ok,” Messing, 47, shared alongside a censored version of the picture that had been sent to her. “RESPECT WOMEN. RESPECT YOURSELVES.”

While Messing confirmed that the initial image came through her Instagram Message Requests feed, this isn’t the first time she’s called out her aggressive males. Earlier this year, the former “Will and Grace” star confessed that Jeremy Piven gave her a make out to remember while shooting an episode for the series.

“The very first day of rehearsal, he shoved his tongue all the way down to my heart,” she said on “Watch What Happens Live” in July. “I was just like, ‘Whoa!’ … Every time, he went for it.”
