>>3015958>>3015974If we're counting "manga but no anime" like most or all of that list, then I have quite a few that you might have heard of and others that you almost certainly haven't.
Youkai Shoujo
Sundome Milky Way (unrelated to Sundome, but the same mangaka as Youkai Shoujo)
Tama Kick
Magicalize (ENF is a little less prevalent here, but there's some; also the same artist as Tama Kick with a different author)
Isekai Sniper wa Onna-Senshi no Mofumofu Aigan Doubutsu (same author *and* artist as Tama Kick and Jikan Teishi Yuusha, far more explicit and gratuitous)
Shiritsu Hakanai Gakuen (decent ENF content early on, falls off later)
Jiken wa skirt no naka de (mostly a psychological drama with ENF-centered themes but very occasional payoff, mentioned here a few threads back)
Ninkoi - Karenbou Hichou (unrelated to Ninkoi without the subtitle)
Cinderella Game (unrelated to the K-drama by that name; hard to search for as a result)
Several much older titles with varying ENF prevalence
Oh! Toumei Ningen
Supeope Chuugaku
Heart Catch Izumi-chan
Ikenai Day Dream
Paradise Gakuen
None of these are LN adaptations as far as I know
