We've got lots of LGBT comics!
In Love Labs, the main characters are both gay trans men! It's based on 80's sci-fi but has a lot more to it than that, I like to think.
The main characters in Mal de Ojo are ALSO gay trans men. This one's more of a fantasy/horror/western
There are also LGBT characters in Between Hay and Grass, although it's a little on the subtler side right now
Fishing Lure is a finished comic with a gay romance as the central theme
We plan on making many more at https://tapas.io/fnflgbtcomics
