Water feels wet because it is highly evaporative. When you get out the shower, you feel cold even on a warm day because the water starts evaporating imeediately. Evaporation sucks heat out of you.
That is what feels wet.
I have bathed in persian Gulf on a humid day, when water temperature is near skin temperature. If you walk very slowly so as not to splash and close your eyes, you cannot tell when you are in ankle deep water. That is because there is no evaporation and the water is not cooling you at all.
Then water does NOT feel wet.

Sorry, but it is purely evaporation and the cooling effect it has on you.
Try it. get your bath water at exactly skin tempertaure. Lay in it almost wholly submerged (any exposed parts will get evaporation effect) and you will not feel wet.
Mercury is highly viscous, but does not feel wet because it doesn't evaporate.

Also, every cell in your body is 90% water. Because cells are closed there is no evaporation, so your body does not ordinarily feel wet. Any wetness from any fluid that evaporates under normal temp and pressure feels wet on your skin, if it is allowed to evaporate. If it doesn't evaporate, it won;t feel wet.
being wet with sweat on a humid Florida day is not the same thing. In that case it is a clammy sensation, quite different from feeling wet. The clammy feeling is your body wanting to sweat from the heat, but existing sweat on your skin is suppressing it because it is not evaporating.

Also, when you are fully submerged in the ocean (scuba diving), you do not feel wet, even though you might feel cold. It's simple - there can be no evaporation in that situation. You do not feel wet, yet you are surrounded by a huge mass of water.
It's only when you get out that you feel wet - when the water starts to evaporate off you.
