Some people get a little indignant seeing the nipple(s) or the derrière of a woman on screen. Perhaps you may not have watched some early B&W movies. They had their ideas of what was acceptable in film, similar to what we might see today, although censorship soon started after a few of these early films.
Maureen O’Sullivan had a body double in the under water scenes. Co-starring as Jane in “Tarzan the Ape Man”, with Johnny Weissmuller (1932), became the first of 12 films in which he starred as the lead, loosely based on the Edgar Rice Burroughs novel.
It was a pre-code film, which garnered enough attention by 1934, to have the scenes, featured in the above link, to be removed. They were later restored for the DVD series.
Maureen O’Sullivan talks about the public reaction after doing a couple of these films. What caused a public furor then, would be a trivial problem today.
For entirely different reasons, I doubt a portrayal of an innocent pairing of two people could be presented in such a manner at this time. Women would be protesting this as a film filled with misogyny and brutish male dominance over women, or something quite close to that description.
A final tribute to a passing era of make believe. A time before comic book super heroes, space adventure, or kids with wands.
The many films of Johnny Weissmuller as Tarzan. A brief vignette.
