All men who take pleasure in surprising you with the cervix dick punch should be punched in the balls while fucking.
I'm not into surprise cervix punching, dick or otherwise. I'm also not into being punched in the balls, much less willing to pay for the experience. I know some people though...
Glad I am not the only one who has smashed there penis into the area between the vagina and the asshole. Never "broken" it to the extend of swelling, but god dam does that hurt.
My sophomore year of college, I lived in the dorms. I shared a tiny room with another guy. We decided to loft our beds so we could put two full sized couches in there and had all night drinking parties until they finally kicked us out for breaking the dry campus rule too many times. Oh well. On to one of the times sex went too horribly wrong: I'm plowing some girl from behind in a loft bed with my head hitting the ceiling with every hump. As she was getting closer to an orgasm, she started slapping her vagina quickly. It wasn't too violent at first but the closer she got to cumming, the harder she started to slap. Eventually she got really wild and started slapping the shit out of her puss. In a flash of a moment the timing lined up that she gave a violent and poorly aimed slap when I was balls deep. Meaning she slapped me in the nuts. I was so surprised and in so much pain that I pulled out and away without realizing I was 6 feet in the air and fell backwards off the loft bed onto the tile floor. The sound of 200 lbs hitting a tile floor was enough to send the RA & Hall Director knocking on my door making sure I was alright. Miraculously I only bruised my tailbone. No I wasn't in the mood to continue when everything had calmed down.
My first time going bareback, I partially tore my hood. It hurt, sure, but it wasn't that bad. Unfortunately, after this I required surgery to fix it (I never could pull the hood back as a kid, but I didn't know that wasn't normal). The following only loosely fits the focus as it's not directly related to sex itself, just the sexual organ. First surgery was minor, only took a couple of days and no issues. However, it didn't fix the original problem. Second surgery was what could be considered a "partial circumcision". However, being in my late teens at the time it was the worst possible time for the procedure, as not only are the nerves (and sensations) fully developed, but you have to deal with unprompted boners and complications due to them. This is spoilered for grossness: Spoiler The following month (yes, a month without even being able to play with it) was a combination of searing pain, and padded underwear to absorb the blood and pus. At least it's in full working order now.
