I don't want y'all to think I'm a prude, though. There was a perfectly good (and educational!) manga from this year that's literally all about sex.
SEX ED 120% (Seikyoiku 120%), written by Kikiki Tataki with art by Hotomura. First published in 2020 and first published in North America in 2021.
PLOT:
Naota Tsuji is a physical education teacher who is also tasked with teaching her students about health and sex-ed. She finds the textbooks deeply lacking, particularly where topics relevant to women are concerned, so she takes upon herself to get in-depth on topics ranging from contraception to masturbation. Her students are eager to learn, much to the eternal mortification of the school nurse Nakazawa.
