Than why does something wet feel different from something slimy or something dry? If you can't actually touch anything, then how would you feel the sensation?

Because you're feeling the force of something, and your nerves send it to your brain for interpretation.

The point that I am trying to make is that the OP's post was incorrect. We CAN touch matter, that is why oxygen can be transferred through our lunges, food can be turned to nutrients, we can absorb chemicals through our skin, etc. It is the electron cloud of the atoms and molecules in your finger that encounters the repulsion of the electron clouds in the atoms and molecules of the thing you are touching that gives us a sense of solidness of objects. So your physical matter IS touching an objects physical matter.

no. The reason you can determine that different types of liquids have different "feelings" is because for each liquid, there are different electromagnetic forces and properties. Not to mention that at a microscopic level, a surface with friction is a surface with a variety of valleys, mountains, and jagged spikes (if you were looking at the surface of the object from a 2D side - perspective). Thus (since the distance at which electrons repel each other is most certainly microscopic), the reason solids all feel different is because they all have different friction constants - meaning that for each ones different "hills and valleys," the electrons are repelling your "hand-electrons" at different points (since, obviously, the electrons at the top of one of the substances peaks would reach repulsion distance before an electron in the "valley"). Your brain interprets (subconsciously, or else everyone would already know this) into the feelings you are accustomed. That is why even two objects with similar friction constants can feel completely different: your touch sensations have becomes subjective since the day you were first able to begin differentiating information by touch.

The force of WHAT though. I could see feeling the actual object regardless of whether it is slimy/wet/dry, but if there is no friction because there is no contact, how can you FEEL it?

Electromagnetic forces. The atoms don't touch other atoms, but the electromagnetic forces do.
