Under My Skin (2020)

Around 24 minutes into the movie the main character Denny 1 played by Liv Hewson admires herself in a mirror and attempts to tuck her breasts under her arms in order to see how she would look with a flatter, more masculine chest. The scene lasts roughly a minute or two, but her breasts are clearly visible while she's adjusting, and then disrobes for a fuller effect.

A man's pubic hair is seen when he pulls down his underwear.
