Pete Wentz has hit the road hard in recent weeks, both with the [article id="1701618"]reunited Fall Out Boy[/article] and solo, on a book tour in support of his new novel, [article id="1702216"]"Gray."[/article] And needless to say, he's learning new and interesting things every time out.

Like, for starters, he probably should have chosen a different title for the book.

"I showed up at a signing in New Jersey yesterday, and this lady was like 'The author of '50 Shades of Grey' is here?'" he laughed. "I think that might have been a little disappointing for her. But I told her 'Don't worry about it, there's just as much illicit sex in this book.' "

Of course, he's also found [article id="1701518"]Fall Out Boy's return to the road[/article] to be equally enlightening ... after all, he admits that no one in the band expected to be welcomed back with the fervor they've witnessed at recent shows. Simply put, there's been nothing but joy in the FOB camp these days, and he and his bandmates are determined to keep things that way this time around, thanks in no small part to their newfound maturity.

"When we got on stage in Chicago, it was crazy. It was a rush, because we honestly didn't think people would care, and that's the truth. But it felt like we didn't miss a beat," he said. "It's so early in the process and things are happening so much faster than we thought; the first time you do things, there's no instruction book," he said. "It's not like 'Oh, okay, you shouldn't act like an idiot.' We're all more appreciative and we've all grown up a bit. It's cool to do Fall Out Boy as Fall Out Men."

Wentz said that the reunion has gone so well that FOB are already thinking about recording more songs -- even though their Save Rock And Roll album comes out April 16 -- but, unlike the past, they won't release anything unless everyone in the band is on board. After all, they're in no hurry to ruin a good thing.

"One of the cool things about coming back was that we decided everyone has to be in on every idea, or else it's out. We did ten songs [for the album], maybe there will be eleven songs on there," he said. "We have other cool ideas, but we're definitely not in that part of being in a band where you're like 'Oh, well, this dude likes this song, so I guess we'll put it on the album, and we'll probably never play it and nobody will care about it.' ... That can happen; and so it feels so good to be so far from it. We're having the reunion sex, so like it's so awesome that we don't have to bring in the whips yet."
