Regrets? John Mayer has a few.

Two years after he opened up about exes Jennifer Aniston and Jessica Simpson -- revealing intimate details about both their breakups and sex lives -- the 34-year-old "Shadow Days" singer realized he probably shouldn't have been so candid.

"I had nothing to say," Mayer admitted on NPR's All Things Considered Saturday. "I was going through a time in my life where I didn't really want to share what was going on, but I didn't want to be boring."

At the time, Mayer told Rolling Stone he had "never really gotten over" his breakup with Aniston, 43, and called it "one of the worst times" of his life. In a similarly revealing Playboy interview, the musician said Simpson, 31, "was like crack cocaine to me. Sexually, it was crazy. . . It was like napalm, sexual napalm."

Now that he's older and wiser, Mayer plans to be more tight-lipped. "When you're just open, but not honest, then you start free-associating garbage," he said on All Things Considered. "It doesn't mean I can go back and scrub it out, but I understand it now."

Mayer's new album, Born and Raised, is in stores Tuesday.
