Most VNs aren't free so you'll have to buy them or torrent them. Most of those we have here on Fuwa, for example Sharin no Kuni. https://fuwanovel.net/novels/sharin-no-kuni-himawari-no-shoujo
The ones that we don't have because we don't host licensed VNs can almost always be found on [no linking or mentioning torrent sites]
 
"Nakige" means "crying game", and is basically a VN that gets pretty sad at some point (not to be confused with "nukige" which is when a VN has more porn than story) while "utsuge" is when the entire VN is depressing, pretty much from start to finish.
Here's a lexicon if you want to know more: https://forums.fuwanovel.net/index.php?/topic/3892-visual-novel-lexicon/

The Narcissu stuff is very good, especially if you like Utsuge.  Yume Miru Kusuri was also my gateway drug into the VN scene (pretty ironic, huh?).  Stay away from Nekoko's route if you're looking for genuine story, but if you like dirty sex scenes that would be a good choice.  Kirimiya's route is also pretty dirty, but there's a really good story to match it.
 
I personally liked Kana ~Imouto~.  One of the heroines is in the hospital a vast majority of the time.  Really good story.
 
Then there's the obligatory G-Senjou no Maou mention, because it's just that good.

A Drug That Makes You Dream has really interesting heroines to pick from, and each of the routes are quite fulfilling and interesting. Also, each route has several erotic scenes spread through out. This seems to fit the bill. I also personally recommend this VN as it was one of my first and got me into visual novels.
 
That said, if you want a story focused on sick/hospitalized people, Narcissu is a great read. Be warned though, Narcissu is really really sad and has no choices or sex scenes.

G-senjou no maou - deep plot, great girls [i just didn't like one], great story, a lot of choices and sex haha
 
Edit: not about disabled girls or happiness, but each girl's route present big issues to be solved by the MC. So expect a little dark stuff happening to the girls :/

If feel exactly like you, i just finish katawa shoujo.... right now..... and i want something like "katawa shoujo" like as you want...

You might want to check out something by Key, for example Clannad or Little Busters. The only thing is that most of Key's games don't have H-scenes (sex scenes) and when they do they aren't very good. If you specifically want something with H-scenes, try Sharin no Kuni or Grisaia no Kajitsu.

My first ever VN was Go Go Nippon, which got me hungry for more VNs, especially Eroges (I think that's the term, I'm new). I played Katawa Shoujo and it was literally the best thing in my life ever, and I was wondering if anybody new of any more VNs like Katawa Shoujo. Preferably in English. I loved the story, I loved how I could choose between girls, which I believe is common in dating sims, but I'm not sure yet. I bought If My Heart Had Wings off of steam but it's horribly censored and the engrish is bad. I tried to install the patch, didn't work, I torrented the game and tried to patch that, and finally, I downloaded a "prepatched version" of the game off of a Russian site, but even then I could somehow load my old saves from the steam version (which is uninstalled), leading me to believe that somehow it didn't work? I mean, every time I think I've patched it, the gallery works just fine, and upon entering Flying Fish Manor the girl who everyone else freaks out about being naked is still fully clothed. So I don't know what to do. Anyways, this ended up being a desperate plea to russanon, but back to the initial topic:

TL;DR, Something like Katawa Shoujo If that's possible? I want a dating sim with deep, unique, characters and dirty scenes Good story would be appreciated too.

Thanks for the help people! I'm really new here.
