... I'll be perfectly honest, I don't see how that answers the question, and for whatever reason your use of tongues and thighs in the description makes me a bit uncomfortable. I still don't understand the difference between "texture," aka "the feel, appearance, or consistency of a surface or substance," and "mouthfeel," aka "the physical sensations in the mouth produced by a particular food."

I even googled it and most explanations appear to boil down to "texture is a part of mouthfeel, but mouthfeel is different," and then say nothing else about it. These articles describe "mouthfeel" using words that are just different textures or tastes, like "oily" or "acidic." The Wikipedia entry for "mouthfeel" even described "texture" as being a synonym to "mouthfeel."

As a result of these last 5 or so minutes of research, I will be taking it upon myself to passively crusade against the use of "mouthfeel," as it makes me inexplicably uncomfortable. Some people hate the word "moist," and I now hate the word "mouthfeel." Any time "mouthfeel" comes up from hence forth, I will be interjecting a quick "gross" into the conversation. Thus is my burden and my cross to bear.

Edit: I hope it's clear that my comment is quite sarcastic, especially towards the end. I'm still not super clear what it means, but ultimately it seems to boil down to some combination of taste, weight, and texture.
