WATCH: Caitlyn Jenner Confronts Her Fear of Wearing a Bathing Suit and Questions Sexuality

“The ability to grow is directly related to the amount of insecurity you can take in your life,” Caitlyn Jenner declares in the newest promo for I Am Cait’s episode on Sunday.

In this upcoming episode, we see Caitlyn confronting her fear of wearing a bathing suit in public as she walks out in a white cutout suit and sits at the edge of her pool.

Last night’s episode showed Jenner admitting to friend Jennifer Boylan that she didn’t feel ready to “expose” herself in a bathing suit just yet, but that “it’ll happen at some point,” and that she was “in no rush.”

Noting that the process of coming out wasn’t something that just happened “overnight,” Jenner admitted it was hard to even say “bathing suit” and that it was going to take time.

In another scene from the newest promo, Caitlyn says “I don’t know” when asked whether or not she’s more attracted to men during a dinner party with several other ladies at her Malibu home.

Daily Mail also reports that Jenner says, “You would feel more feminine if you were with a guy…I can appreciate the male form,” to the surprise of some of her friends.

Of her orientation, Jenner had previously told Diane Sawyer back in April “I am, as far as I know, heterosexual…As far as I know, I’ve never been with a guy. I’ve always been married, raising kids.”

As explained by Human Rights Campaign, “A person’s sexual orientation is distinct from a person’s gender identity and expression.” Furthermore, as explained by GLAAD, “Gender identity is one’s own internal, deeply held sense of being male or female. Sexual orientation is who one is attracted to. They are not the same thing and should not be conflated or confused.”

So far on I Am Cait, Caitlyn has been seen growing close to friend and actress Candis Cayne. On last night’s episode, in light of rumors that her and Cayne are more that just friends, she revealed “Candis is a beautiful woman, but as far as dating in the future, I have absolutely no idea.”
