Than why she must be locked as lesbian, considering the lack of options for romance in this game? What is the point? She is not a real person, she is NPC in the videogame, so-called "sexuality" doesn't make this (or any) character any deeper in case there is no story related, in case of Cyberpunk straight/gay is just a tag. Besides, Judy triggers on body type only, and this lesbian it pretty fine with tits + dick combo, which makes her locked sexuality even more questionable.
Still don't see why every romanceable character can't be bisexual, there are only 4 of them for fuck sake. It will not ruin roleplay, moreover, it will improve it. In playthrough of one player she can be sweet to female, in playthrough of another - to male. I don't understand how in can ruin the game experience of the first player.
Genitals dont matter in the game so yeah, it's pointless. She still sees you as a woman with a vagina. Also the reason she must be locked as a lesbian is the same reason why Panam is het or River or Kerry is gay. Because they decided so. And because she's lesbian.
What we need is more bi romances for sure, but not to existing characters. She's lesbian.
