>>3694048it's about creating the illusion of intimacy, that there's a bond between streamer/viewer and that the viewer is special. there's plenty of relationships streamers can have with viewers that elicit a similar reaction: imouto experience, onee-san experience, etc.
>>3691858it's pretty obvious that males can't provide GFE but BFE is absolutely a thing. among the Holostars you have Oga, Shien, Temma and Miyabi that all lean on it to various degrees - especially in Twitcast streams which provide a smaller and much closer experience.
there's a number of vtubers I've run across, agency and indie, that use Twitcast as sort of a alternative venue for GFE or similar streams regardless of whether they could do it as a membership stream or not. Twitcast can be used from simply their phone without a camera which allows it for other venues - rolling around in bed, in the bath, etc.
