Will Ferrell has admitted that he lost his virginity at the grand old age of 21.

The 44-year-old comedic actor opened up in the latest issue of Rolling Stone about his college escapades.

He recalled that he finally became intimate with a woman during his junior year of college and revealed advice he received from his mother.

"In my mind's eye, it seemed like the way it was supposed to happen," Will recalled.

He shared that his mother actually believed he had lost his virginity earlier with a popular classmate.

"She said, If you slept with this girl, you'd better slap a condom on that pecker of yours,'" he laughed.

Will is now happily married and has three children but says that his revealing antics on camera in movies like Old School where he bared his butt, is just a mirror on what he used to get up to in his younger days.

"In college, they had this thing where you'd run naked on fraternity row, and if anyone challenged me, I'd be happy to do it," he revealed.

Will is once again showing skin in new movie Casa de mi Padre where he says he felt bad for his makeup artist.

"Someone had the either wonderful or horrible task of putting makeup on my a*s," Will shared. "This kind of thing is not a big deal to me."

The Saturday Night Live alum also spoke about his hilarious new role.

"I can't tell you where I first thought of Casa de mi Padre and I can't tell you when, but a light bulb went off that said putting me in a Spanish-speaking movie with the cast being entirely Latino, and myself playing a kind of Latino actor, and the joke not being that I'm speaking poor Spanish, that it would be hilarious," he said.

"I guess I did it specifically to raise the question, Why did you do this?' It's one of the craziest things I've done."
