observation kink ???

anyone have this thing where they want to be like observed, idk how to describe it but like, i want someone to notice the different ways certain acts affect me. i want them to try things out not for my pleasure but because they want to see what it does to my body, and then also comment on it.

for example id want someone to just try a bunch of different dildos. not necessarily staying with something for long, just trying different depths, angles, speeds etc, and comment on how those things are affecting me 😵‍💫😵‍💫 after using a large toy i find myself wanting to ask if im gaping but i dont want to ask i want it to just be said lol

if anyone knows what something like this might be called i would love to know
