"Everyone should try a little bit of something new in the bedroom," the singer says. "It's definitely fun when you bring some whips and leather and whatever you may be into -- a little bit of S&M -- into the bedroom."
Jonas should know -- after all, he wasn't shy about discussing his personal experience with some play gear.
"I wrote it about me and someone I was getting wild with, and maybe (we) busted some outfits out -- you know, you get a little crazy," he says.
And even if you don't know, Jonas is happy to be your Christian Grey. "I'll do a handbook," Jonas joked.
Now 27, Jonas professes that being an adult has him feeling more liberated than ever, both musically and sexually.
Though he is "proud of the stuff I did with my brothers," he asserts, "I feel like I'm free in my life to speak about (sex),"
Elsewhere, Jonas admitted that his new beefed-up bod has recently driven more traffic to his Twitter, where fans message him their scantily-clad pics.
"Sometimes there are crazy ones -- just straight nudity," he says, noting that many of those DMs come from gay men, which, "I take as a compliment."
Jonas says he's also complimented by longtime gay rumors about him. Chalking it up to the fact that he's "in touch with his feminine side," the singer's not fazed.
"I don't mind," he says. "Hey, if they wanna think I'm gay, it's fun."
Should he play gay like brother Nick, who's starred as a gay character on both Kingdom and Scream Queens, he says his co-star preference would be Daniel Craig, Matthew McConaughey or George Clooney. An "older, mature" man, he noted.
