Can science explain why girls (males) like myself are also commonly into rape play?

physicsfags pls halp

I can't understand why, when I have a spherical shell with an electric charge distributed on its surface, the electric field E = 0 inside of it, and therefore, for any given charge inside of the shell, the net force F = 0. I mean, ok, I can use Gauss theorem etc. to prove it, but I don't get it intuitively.

Using for example a positive charge distributed on the surface, and using a positive "explorer" charge on the inside, if I put the charge in any position but the center of the sphere, wouldn't the net force move it until it reach the center (because it is closer to one "side" of the sphere and further from another, so the force will be respectively greater and weaker)?

If I throw an object straight up in the air (vertical direction), will it take more time for it to go up or to come down? I know that the time is the same if it's done in vacuum but I'm a bit confused otherwise...
