His biggest turn off? Baby talk!
“[It’s] terrible,” Viall, 35, tells PEOPLE exclusively. “Like, nothing will ruin a moment like baby talk. That is not good.”
Another no-no? Tardiness.
“I don’t like being late,” he explains. “I mean, it’s not the be-all, end-all – and I’ve never smoked a cigarette. That’s pretty gross.”

At the end of day, there’s just one thing Viall is looking for in his future wife.
“I mean, I’ve always been attracted to genuine confidence,” he says. “I think sometimes that’s hard to figure out. Sometimes people can seem very confident, but then … not so much.”

He’s also looking for someone with a “strong personality,” though “that could also vary too,” he says.
“I have a big personality,” he admits. “I can be a lot to handle, and I need someone to be able to challenge me, and not in a negative way where they get frustrated, but more that they can keep up. I want someone who wants me to do the same.”
The Bachelor returns to ABC in January.
