I've been looking at the UMD and wet and messy photos for many years. Of course we all know there are a million sub-preferences within WAM, but I think I may have a handle on some of this.
1. There is often a level of ruination in a wam video or photo. What I mean is the model gets ruined in some manner, whether it be clothing, hair, makeup, etc. This is also where the humiliation factor comes in.
2. There is often a level of fun, sensuality or sexual fun, but not always. It might be a woman discovering a mud pit and shedding her clothes and having wild fun.
3. Often there is a combination of 1 and 2. In this scenario, a girl gets hit with pies, but then starts to enjoy the whipped cream on her body. Perhaps three girls discover that mud pit, and two of them throw the third one in. She goes from 1. to 2. and maybe pulls the other girls ankles and causes them to also fall in, where they can go from 1. to 2. as well.
More about these two areas of wam stimulation:
1. The Ruining. On the mild side of the scale, we have water. A girl on the beach getting a pail of water on her is mild, as she was already at the beach and dressed to go in the water. On the extreme end of the scale, we might have a girl in very expensive looking clothing, perfect hair and makeup, becoming totally messed, whether through pies, mud, slime or whatever. If getting messy on the outside isn't enough, there is the force-feeding of messy food substances, and even paint in the eyes (some Asian videos) or playing with a messy dildo. She might even be tied down and have this happen against her will. Of course the ultimate ruining is when a quicksand girl submerges and is presumed to have died.
2. The Fun. For this aspect of wam, the model is enjoying every minute of the experience, loving the feeling of the messy substance on her body, perhaps rolling in it, rubbing it all over herself, and maybe masturbating. This may start with her clothed, and then showing her stripping off the messy clothes, but the emphasis isn't on 'oh no, my new dress', but on 'on yes, this feels awesome'.
I think we are divided with about 2/3 of us being type 1, and 1/3 of us type 2. (with a whole lot of crossover of some of each element)
So personally speaking, my type 1 (ruining) interests are mild. I do like to see some surprise, such as a girl falling into a mess, or being playfully attacked with mess. I've no real interest in the clothing being ruined, though I love the look of thin fabric stuck to a woman's body with some messy substance, until the clothing comes off. I'm mostly type 2, but I don't need to see vibrators or crotch shots. A girl in a thong having fun is as far as I need to see, or if she's nude but without the spread leg shots.
I know we're all very different. I rate my preference as Type 1 - level 1 out of 10, and Type 2 - level 7 out of 10.
I hope this makes sense to everyone. If it does, it might be interesting to see who is into what, based on this system.
Ditto, my type 1 factor you describe is pretty low, maybe a 2 (I like seeing clothes get messy ruined, but don't care for ripping etc).
Type 2 is where it's all at for me because WAM is sensually and sexually connected to me. I'm more about enjoyment (visually and tactilely). So my enjoyment is being involved, and the partner not hating every minute of it.
I'm sort of 1 and 2 combined. I like the ruining of clothes, make up and hair, this extends to clothes ripping, with lots of "oh no, not my dress or hair" type of dialogue changing into fun and sensual enjoyment as soon as she realises that she's been trashed a kind of "sod it, let's go for it"
