Basically, you can't bend your fingers back to make him feel good. You bend it towards the front
How are they suppose to do that they just draw
The artist drew the seme bending his fingers inside the uke backwards, which wouldn't make him moan in pleasure

Ohhhhhh I see! Ok took note of that. Why woulndt you get pleasure? Is it just a tickle then?
Ok so I researched a bit more, and you can get pleasure from the anus because it still has nerve endings, however the prostate is definitely the hotspot for the pleasure zone.
I got this from an article: "Initially, prostate stimulation might make you feel like you need to pee a bit, but this is just your body readjusting to a sexual response from stimulation."
I'm not sure what it would feel like without the prostate, and in fact women don't have prostates so I'm not sure if it would be ticklish or not.
One thing that always annoys me is then the artist draws the prostate on the WRONG side of the body.
The prostate is ALWAYS between the rectum and the peen because it controls the semen flow in the urethra.
