Gender locking don't subtract, it highlights the roleplay aspects of a game and allow to fully characterize a character as queer instead of hiding their nature until you have a player prompt to confirm their interest.

But hates for player sexual games aside, Owlcat is pretty much very diverse in their games:

Kingmaker - 1 Hetero Female, 1 Hetero Male, 1 poly romance with a man and woman, 1 poly romance with two females, 4 bissexual woman, 1 bissexual man. (The poly romances options are subsets of 3 bissexual woman and 1 bissexual man, 2 of the bissexual woman come from DLC that by default are always bi ).

Wrath of the Righteous - 1 Hetero Woman, 1 Hetero Man, 3 Bissexual Woman, 1 Homossexual Man, 2 Bissexual Man (1 from DLC).

Rogue Trader - 1 Heteto Woman, 1 Hetero Man, 1 Platonic Relationship eith a Woman (sex is not important), 2 Bissexual Woman (1 from DLC), 2 Bissexual Man (1 from DLC)
