…because they make you cringe? Mine’s cock. No idea why, I just dislike the term. A lot of my friends take issue with the word moist..
“Cock” and “dick” don’t bother me… they’re both better than something goofy like “wang” or sterile like “penis”.
I do try to avoid “moist”, though… that seems to be almost universally disliked, and makes me think of brownies.
