Giant stick man person

In this world people are like blank Mannequin people in the way they don't have any defined traits, they still have mouths, when they're mouths are closed it looks like a blank circle for a head kinda, some still identify as different genders but clothes are kinda just a suggestion because they don't have any visible genitalia unless they specifically want it to appear for a reason, although they do come in maybe different colors but it's not a ethnicity or race thing it's just that people are born different colors, they come in many different sizes from small to normal to giant, they seem to not speak much but sometimes do, they don't speak much because it seems they are telepathically able to convey what they want. Sometimes the larger ones and smaller ones like to try out different sexual stuff like safe vore, stuffing a tiny one up their ass or other possible holes, or even stuffing someone down their urethra.
