"I wore these little thongs that literally go up your butt, and it definitely takes getting used to," Manganiello, 35, told People at a boutique opening in New York.
The actor, who had never worn a thong before the Magic Mike shoot, explained his discomfort at the tiny strip he had to sport in the dance numbers.
"It was uncomfortable at first. It sort of felt like a wedgie," he said, "but once you get into the routine of wearing one, you know what to do and you just do your thing. We all had to suffer a bit for our craft."
Now that the beefy, 6-foot-5 actor has experienced the revealing underwear first-hand, Manganiello has a newfound appreciation for what women go through for sex appeal.
"I have so much respect for all women who choose to wear them," he said, laughing. "It's not easy wearing one."
Despite his barely there movie "uniform," Manganiello added that he didn't feel self-conscious parading in a G-string in front of his costars Channing Tatum, Matthew McConaughey, Alex Pettyfer, and Matt Bomer.
"No, we all took our turn in the barrel," he said. "Being with the guys, nobody takes them self too seriously. Everybody was on set cheering, laughing and rolling on the ground."
The actor is a bit shy, however, when it comes to his family seeing him in the steamier scenes of the movie.
"I told my parents not to go see this," he said of the film, which hits theaters June 29. "Nothing can prepare them for what about they are going to see."
