At this rate, the developers at CD Projekt Red are likely going to keep getting asked about Cyberpunk 2077's character customization in every interview leading up to the game's release. After an interview from Tokyo Game Show (TGS) 2019, we now know how the recently revamped body and voice options impact the game's sex scenes: your character's genitals are locked to the body type you pick.
Speaking to VGC, level designer Max Pears clarifies how your character customization will be reflected in the game's sex scenes, which will feature nudity and, like most of the game's cutscenes, will stick with a first-person perspective. CD Projekt Red is separating the option of picking a "male sounding" or "female sounding" voice from picking a body type, but genitals cannot be changed independent of the body type you pick. "We have the body type you select, and then the genitals will be determined by that." Pears also told VGC that NPCs will commonly refer to your character by name as V rather than by gendered pronouns.
Thanks to a recent developer Q&A, we also have a better idea of how NPCs will react to your character's cybernetic body mods. In a thread on the official Cyberpunk 2077 forums, quest design coordinator Philipp Weber sheds light on how NPC reactions in game's quests change (or rather, may not change) based on the cybernetic modifications a player has installed. "In 2077, body modification is fashion and it's a part of everyday life," Weber explains, noting that while reactions can "sometimes" change based on the kind of an NPC and their status, "there's really not many 'purists' running around." Mods are so "completely normal" in Night City that Weber compares "not having enhanced cyberware [to] not having a smartphone nowadays."
If you need a better sense of how character customization impacts the moment-to-moment gameplay, CD Projekt Red recently released a 14 minute cut of Cyberpunk 2077's E3 2019 demo.
