Well, you know F/SN, don't you? Ahaha, but there's also a few others I've played. Not a lot though. I'll list the ones I'd recommend more first.
Sengoku Rance - NOT a VN exactly, but an eroge with VN elements, although it's primarily a strategy game. Really quite fun, has tons of H-scenes with almost every unique female unit. Kind of difficult though if you don't know what you're doing, you might want to have someone to talk to who's played it before.
Sharin no Kuni, Himawari no Shoujo - I haven't finished the whole game but it's really good so far. (It's not worth playing through more than once though, I've heard, so make sure the girl you choose is the one you like the most.)
Wanko to Kurasou - Loli dog girls and stuff, but people often complain there's too much H-scenes everywhere. (Nadeshiko route first if you plan to do both routes.)
Yume Miru Kusuri - It's pretty famous, I've done one route so far, and I'd say it's okay. I lost interest in it after I finished the route I wanted to do though.
Sekien no Inganock - I've heard from someone else that this was pretty nice, but I haven't gotten to playing it myself.
Kira☆Kira - I haven't played this either but it has good ratings on vndb, and someone recommended it to me.
Err... That should be enough for now. Sengoku Rance can be pretty long on your first playthrough, and Sharin no Kuni isn't that short, although it will only require one playthrough. Wanko to Kurasou isn't that long though (or maybe it's because I played it everyday). YMK isn't all that long, but will take some time if you do all 3 routes.
All of these should be on FAKKU!, you'll want to register if you haven't already, then look for the User Uploads section, then in the VNs section, and there's should be a thread stickied that has a list of every translated VN uploaded for FAKKU! there.
I know some more though if you manage to finish these or decide to look for others. Give me something specific you want and I might be able to find something, too.
