Dylan Mulvaney, a transgender creator who has chronicled her transition with her "Days of Girlhood" series, on Sunday responded to a slew of Caitlyn Jenner's tweets in which she commented on Mulvaney's body.
Mulvaney said what prompted the response was one of Jenner's tweets, in which she said, "He is talking about his penis!"
Mulvaney then pulled up a screenshot of a different Jenner tweet, in which she wrote, in part, "Dylan...congrats your trans with a penis."
In the video, Mulvaney said the experience made her realize that transgender women should not feel compelled to avoid wearing tight pants or tuck their penises.
Prior to Mulvaney posting her video, Jenner said in a tweet she had "never received more death threats."
