Nick Jonas is getting super candid about his sex life once again.

The "Chains" singer sat down with Andy Cohen on Tuesday's Watch What Happens Live!, and opened up about everything from his kinks and fetishes to his rumored high-profile romance with Kate Hudson.

Running down a list of his sexual proclivities, the 23-year-old singer didn't shy away from talking about the things that turn him on -- which "maybe" include voyeurism – and the kinks he's got no interest in -- basically everything else.

While Jonas says he's "not into" watching porn with someone he's dating, and he "never understood" foot fetishes, he did admit to getting tied up to a bed post once, but said it "didn't end well."

"I didn't know what to do," Jonas recounted. "It was all bad."

While he might not being into anything too crazy, Jonas revealed that he would "absolutely" be down for getting spanked, adding, "I've got a firm ass."

The singer was certainly candid about his sex life, but clammed up when a WWHL caller asked, "All the viewers want to know, what was the last thing you texted Kate Hudson?"

Jonas and Hudson have been rumored to been dating, off and on, since September 2015. The couple have been spotted having dinner numerous times over the months, and were recently seen dining at the same New York City eatery in early May.

Jonas played coy about the question before divulging the contents of his last text to the 37-year-old actress: "Hope you're well."

"Oh, ok. It wasn't like, 'Hey, I left you sleeping this morning cause I had to go,'" Cohen prodded with a laugh, before adding, "I told you before the show that I like it when hot people do it. So I'm hoping that the two of you are or did..."

Jonas neither confirmed or denied Cohen's less-then-subtle prompt and played the moment off by comically wiping sweat off his brow and taking a dramatic sip from his margarita.

The Kingdom actor was joined on WWHL by Hamilton star Leslie Odom Jr., who took home a Tony Award on Sunday for Lead Actor in a Musical. After a few drinks, the celebrated thespian opened up with Cohen about the infamous incident between Madonna and Hamilton creator Lin-Manuel Miranda.

Odom was asked what audience behavior made his "blood boil," and the 34-year-old actor revealed it always upsets him when people are "disconnected" from the performance by playing on their phones -- which is reportedly what got the "Rebel Heart" singer in trouble with Miranda.

During an off-Broadway staging of Hamilton in April 2015, Madonna allegedly used her phone repeatedly during the performance. Miranda later tweeted, "Tonight was the first time I asked stage management NOT to allow a celebrity (who was texting all through Act 2) backstage. #noselfieforyou," though he later deleted the tweet.

While Madonna's rep denied the reports at the time, Odom sheepishly admitted to seeing the incident go down. "[It] was a 300-seat house, so you see a face lit up. There's like a halo of light. It's distracting and it's disappointing," he recounted.

As for Jonas' raunchy confessions, this isn't the first time he's talked about getting tied up. The singer recently joined Demi Lovato and James Corden on an amazing installment of "Carpool Karaoke," and things got dirty, fast. Check out the video below to hear more.
