I've been loving all the themes here

but I'm definitely biased toward wet men. Nice touch having the water source absent.
My list of 13 isn't pics (hey, there’s no rule against that!), but I’ve included a few visuals anyway. Below is a selection of the 13 sex words most frequently appearing in my latest erotic story. To keep the list to 13, I’ve left out several that were used fewer than 4 times. I also didn’t include some of the words that aren’t inherently related to sex, even if I used them that way (e.g., table, 7 times). Word frequency counter:
http://www.writewords.org.uk/word_count.asp They also count phrases.
Top 13 sex words in my recently-submitted manuscript
cock - 17 times
ass, asshole - 14 (12, 2)
fuck, fucked - 12 (7, 5)
lube, lubed - 6 (4, 2)
hard, harder - 3 times each
paddle - 6
wet - 3
stroke - 3
fingers - 3
dick - 3
balls - 3
throat - 2
thighs - 2
Some of the others used twice: sweaty, submissive, prostate, jerk, hung, horny, hole, and foreplay. I considered counting "hole" with "asshole", but I think of it differently. For myself, I’d put “sir” (15 times) on the sex list. Interestingly (at least to me) is that I used the two main character names (other than the narrator) almost equally as I’ve done in almost every story I’ve written. It’s not conscious, but I tend to do that, even with three main characters.
My regular photo source has mostly gifs now, so I haven’t been saving much. A few random stills:
