Caitlyn Jenner's documentary series "I Am Cait" premiered Sunday on E!

The reality TV star took a road trip with transgender friends to San Francisco, California, including actress Candis Cayne.

In the video clip, the 65-year-old packs for the road trip. While choosing clothes from her closet with best friend Ronda Kamihira, Kamihira teases Jenner, "You need a sexy [outfit] for Candis."

"Who's Candis?" Kamihira's daughter asks. Jenner blushes.

"We're not going there," Jenner says with a smile. "[She's] a girl that's going on the trip with us."

"Do you find her attractive?" Kamihira asks.

"She's a very attractive lady," Jenner admits.

"These girls won't give up," Jenner says during one of the episode's confessionals. "Candis is a beautiful woman, but as far as dating in the future, I have absolutely no idea."

It sounds as though Jenner has left the door open for dating Cayne.

It was rumored that Kamihira, who is also Kris Jenner's bestie, was dating Jenner when the former Olympian was still living as Bruce. The paparazzi took several photos of the pair together, but the two are just friends and Kamihira was one of the first people to know about Jenner's sex reassignment.

"It was so great when I found out," Kamihira told Jenner's transgender friends during the road-tripping. "One time you called me and said, 'Hey what are you doing,' and I was like 'Nothing.' And you were like, 'Well, do you want to come over for a glass of wine?' And I was like, 'Yeah, of course.'"

She continued, "I'm thinking, 'He's not gonna hit on me?' Caitlyn told me her story that night after a couple glasses of wine."

Jenner packed bathing suits for the road trip, but did not wear them. She told producers during an interview that she can barely say "bathing suit" much less wear one in public. That's gonna "take time," she said.

Fans also learned during Sunday's premiere that vocal surgery may be in Jenner's future. She has endured many surgeries and physical changes for her transition, but her voice remains the same -- something Jenner is unhappy about.

Jenner then told her step-daughter Kim Kardashian that she was considering surgery.

"What if they made a mistake and you had no voice?" Kardashian asked.

Watch "I Am Cait" that airs Sundays at 8 p.m. ET on E!
