"I don't know if you ever will," he joked while speaking with ET's Lauren Zima at the "Women Tell All" taping last month. "[I'll reveal the status of my virginity] in 10 days, 10 years, [or] never. I don't know."
Sydney Lotuaco, who was known for her cheeky sexual innuendos on the show, wasn't afraid to ask Underwood about his virginity on "Women Tell All."
"I think that's the question we're all asking. Someone had to do it, and that was me," she said, adding that Underwood has gotten "good" at dodging questions about his sex life.
"I guess whoever might've taken [his virginity] would know, but I don't know," Lotuaco added. "Maybe the camera crew."
"Right. I mean, the story isn't over yet, so there's still a few more episodes for the story to play out," he offered. "I don't know [if viewers will find out if I'm still a virgin on the show]. I haven't seen [it]."
"I'm right there with you. I'm living it with you, so I'm really eager to find out if I'm still a virgin or not," Underwood cracked.
After his dramatic breakup with Cassie Randolph and subsequent jump over a fence, Underwood still has a few loose ends to tie up as The Bachelor. His two-night finale airs on Monday and Tuesday at 8 p.m. ET/PT on ABC. Join ET's Bachelor Nation Facebook group here.
