Beauty is pain for Matthew McConaughey when it comes to his new role as “Dallas” in Magic Mike…

Before he took on his role as an exotic dancer in the upcoming movie Magic Mike, his privates got a little pampering.

The 42-year-old newlywed talked about his wild waxing with Jay Leno last Tuesday.

“She’s pouring this glue and stuff all over you,” he recalled, “and you’re sitting there and you’re giggling, and all the sudden she lays something on you . . .and it hurts.”

Matthew says he laughed through the pain of it all. It’s all worth it because the actor will be featured in the film wearing buttless chaps!

Magic Mike hits theaters June 29th.
