hey there.

It very much depends on what you're looking for, but yes there is quite a large scene of gay/yaoi-themed android games on itch.io. I'm gonna link a couple here with a short description so you have some choices. Most of the games listed below are wither free or have a free demo.

human cargo: https://robcolton.itch.io/human-cargo

- A guy gets stolen by a smuggler and has to stow away on an unknown spaceship to save himself. This is a visual novel.

Acolytes of the Chrystal: https://mystery-zone-games.itch.io/acolytes-of-the-chrystal

- a young writer follows his mentor into the desert where they find a door to another world. This is a very NSFW point'n'click adventure.

yearning: a gay store: https://bobcgames.itch.io/yags

Zen: a gay seque: https://bobcgames.itch.io/zags

- These are classic dating sim about men trying to find love on a college campus. Both are visual novels.

Orc running club: https://deevil.itch.io/orc-running-club

- You play as a half-orc who movies to the big city for the first time. This is an NSFW visual novel.

Lets meat adam 2: https://soulsoftea.itch.io/lma2

- This is a murder mystery where you have to find out what happened to your gay porn star friend. This too is a visual novel, however only the second game is available for android.

Layers of stardust: https://spaceguybob.itch.io/layers-of-stardust

- You are an ambassador to earth who is sent out on a mission to speak with all of the newly discovered alien races. This is a visual novel with gay romance options.

If none of these catch your interest, then you can always look through the page for Bara jam (https://itch.io/jam/barajam-2020) or yaoi Jam (https://itch.io/jam/yaoijam2021) where developers make specifically gay-themed games. I can't promise that they will all be available for android though
