I’ve used it as a euphemism for horny, too. Had no clue it held so much ooginess for so many. 
It depends on the usage - post # 18 is right out - but I feel like this, too.
But I can use it to describe cake just fine without cringing.even a little.
Nah. It’s just a woid.
This suffers from the thing where, if you repeat almost any word out of context, it starts to sound weird. I think it was Bill Cosby that did it with “obey”.
“It sounds like pig latin.”
Doesn’t bother me. I think it can soudn kinda hot, when used right.
It does sound a bit tinny…
Oh, look, antelopes!
Only in one context. You still want your turkey to be moist when cooked, eating cake that isn’t moist is a drag, and nobody is going to think you have horny eyeballs if someone remarks that your eyes were moist after you heard a sad story.
What the heck is wrong with panties?
But together? It breaks the oogymeter.
Mine is “slacks”. I think it’s because I picture chubby men in the 1970s with lots of chains, wearing polyester slacks. I shuddered just typing the word.
Mmmmm…moist.
Sorry, what?
A friend of mine always says, “The night was moist.” during a humid summer night. He’s quoting “Throw Momma From The Train”.
Now that I know it’s freaks people out, I will use the word “moist” more often.
So how do you guys feel about “juicy”? 
Moist panties.
Uuughhh. Makes me want to go change my underwear, just thinking those words.
Moist? phooey. How about “soggy”
I can’t explain it, it just is cringeworthy. It’s probably my least favorite after a bunch of offensive vulgarities.
Wow. One more example of how out of the loop I am. Neither ‘moist’ nor ‘panties’ oogs me out. In fact, it has never even occurred to me that anyone could be ooged out by a word.
Thinking about it, the only word I can think of that oogs me the least little bit is ‘cum.’ And that’s just because of the spelling. Say it out loud and I’m cool; use it in writing, spelled ‘come’ and that’s fine too.
Edited to add: Oooh! I thought of another – ‘luv.’ Like ‘cum,’ it’s the spelling. Call me ‘love’ out loud and that’s fine, call me ‘love’ in writing, that’s fine too.
Wet?
What about “sopping”?
I can’t think of any word that bothers me, either to say or hear. And I’ve never known anyone who had a problem with “moist” … “cunt,” yes, but not “moist.”
But that doesn’t explain why it would affect people who just hear the word, right?
