It's got plenty of gay content, as well as pretty much everything else you can think of and some you can't (
e.g. anthropomorphic skunk melting into you as you fuck her and becoming your new midsection. Yeah, didn't see that one coming...

No, they are exclusively focused on interactive fiction. That is, text-based games in which you type in your commands (usually). You might come across an image or two, but it's mostly walls of text. Not much of this stuff is being made anymore, save for BBBen and the Flexible Survival crew. Unless you count Twine and similar engines, which I gather is a topic of some debate.
