1) Your age, please?
20
2) At which age did you start masturbating?
14ish I guess
3) Try to describe, how your cunt juice is tasting like!
It's not too good, I don't really like to taste it. It's usually not sweet. Just, sour maybe. Maybe it tastes like feet. 
4) Does your cunt provide any prominent features (e.g. large inner lips, saggy outer ones, big protruding clit or gaping cunthole, ...)? If so, name them!
Bigger pussy lips. It's darker than my skin.
5) Which is the most unusual thing that has ever been inserted into your cunt?
Ginger pieces
6) Have you ever felt ashamed for the way your cunt is looking like? Did you enjoy it?
The change in skin colour looks odd, I think. But not exactly makes me ashamed in any way.
7) Have you ever flashed your aroused cunt in front of people who know you (e.g. neighbors, friends. family members, classmates, …)? If so, name them!
Nope.
8) Have you ever had any taboo or really bizarre fantasies? If so, name them!
To be dominated by like, 3 dominant people, at once. Preferably two females and one male. Lots of humiliation. 
9) Does your cunt enjoy a certain amount of painful punishment? If so, which kind of?
Enjoy? I don't think so. I like the Vicks feeling.
