Fingertip's Love
This mangaka really likes to write about older characters with younger men. I didn't think I'd like it so much as a genre but he/she has me loving her stuff!
Finder
Beautiful graphics and some hardcore scenes. Romantic and suspenseful enough to keep my interests too. I tagged switch tag because FeiLong gives and takes :) Update vol9 ch56: the art/graphics are getting more comical, less detailed. Ukes are beginning to look like cutesy kids. Still enjoying it though but skimming through boring parts now. Update ch84.5: dropping rating to 3.5. It seems that the mangaka is just going along with fan service and forgetting the original concept of this story. I’m good with that, but not enjoying it as much as when I first read it.
Iketeru Police
No actual real sex scenes as of yet. Just graphic fantasies that don't really do much for me. This one could be read and enjoyed in small doses as the slap-stick comedy and try-hard Ecchi scenes can get a little old. Had some tame yuri aspects to it too.
Kono Yoru no Subete
2.5 stars. To read before Donten no Hekireki (Doujinshi)
Black Sun
Border
Definitely more on the action/suspense side than smutty. Love it and love this mangaka! No sex between the 4 MC's yet, but a few scenes outside of that.
Hantsu X Torasshu
DNF @ ch24 pg6. Definitely a manga targeted at teen boys. Lots of cheap panty and boob shots and some Ecchi teasing mostly. There were some entertaining moments but I skimmed through most because this just wasn't my cuppa.
Shutendouji
DNF @vol1 ch2 pg1. Not my jam. More of a 90's art, shounen/action read about demons. Just a personal preference and not trying to take away from the mangaka.
