I am gay. I know bears are a thing I just hate that the mass majority of games seem to just be bears and daddies.
Honestly speaking, of all the gay games I've played, the artwork usually focuses on one spectrum of male body types. Bara games will have bara bodies, and yaoi games will have yaoi bodies. There's rarely a game that casts a wide variety of body builds.
Unless we add in furry games though. In furry games there are some games that have shota dogs, lithe cats, chunky bears, muscular tigers and bodybuilder gators.
The mass majority of non-furry gay games will probably stick to a single archetype since its what appeals to their patreon audience. Its a shame we don't get as much diversity like straight games that tall vs short women, big-breast vs flat-chested, and other intricacies which I probably don't notice since I'm not straight. But gay games are still a relatively new niche market, so you won't often see one that'll really hit all your buttons.
Mimimimimimi, what else do you want?
Twink, fairy like characters that are basically women and stripped of all masculinity?
If so, how about you look up straight porn games.
Even in straight eroge, there is a remarkable lack of male detail and usually focuses on the female art. Gamerboy probably wants something that isn't as muscular as Black Hoops or Meatlog Mountain.
There's muscular shota, which you can have plenty of with Camp Buddy.
There's the leaner, but still somewhat muscular bodies of Coming Out on Top and YAGS.
There are yaoi games, which I don't really prefer but whatever like Hadaka Shitsuji. These have your twinky, pretty-boy looking fellas.
Personally, I prefer the lean muscular types of Black Monkey games, but I still enjoy myself with these big daddies. At this point, I'm really more into the world-building/story that goes into these games rather than the hentai.
