I've had all the above.

Seized up leg muscles from doggie.
Lower back getting thrown out. I've had lower back problems since i was 22. If I'm consistently working out and going to the chiropractor every month I'm all good, but if I skip out this shit hits me pretty hard.
Burst blood vessels, leaving huge bruises that look horrible. These are the worst when you have a rotation and all of a sudden you have to cancel plans with a chick so she doesn't see a giant black/purple patch on your cock
Hitting girls IUD sucks.
Gotten cuts here and there where the skin tore cuz the girl wasn't wet enough. These are usually the result of an evening with too much alcohol and/or drugs.

Lower ribs and abdomen hurts for a few days after. I don't know why.

One time I was banging this girl in my friend's parents' bed. My foot had one of those random sharp pains and I squirmed all over the place in agony. She told me I had an intense orgasm face.

I'm proud to say I've never had a dick injury. I even have three pairs of cheap ass billabong short I got in Thailand that will catch your dick zipping DOWN and even though the skin is caught in the zipper I have no damage. After reading all these haphazards I consider myself licky

Was banging a chick from behind (laying down on top of her, not reg doggy) and as I came I stretched my legs and one of them started cramping really bad. Like double-ot-game-of-basketball-cramps bad. The look of extreme concern in her face was priceless though.

(This was morning sex and I did drink a lot the night before so it was prob due to dehydration)

I had a girl riding me and I was whipping her ass with my belt. The belt wrapped around her ass and hit me in the balls.

Be careful in cowgirl.

If she pulls up too far and you slip out and she slams back down that's it for your cock.

I popped the base of my penis (a minor penis fracture) during sex but continued to bang the chick because I was murdering a dry spell and I was pretty drunk. I looked at my cock in the morning, it was swollen and it hurt to piss. I couldn't sleep on my stomach for a week!

I also cut the tip of my penis face fucking a chick. Still got the scar.

[Timoteo]

I got a nasty scrape from a bad handjob (and that was the last time I got one - I still have the scar), and had the skin tear a little at the tip (I can't recall how it happened). I've definitely gotten cramps in my hamstrings on more than one occasion. When you're trying to get leverage, you tense up your leg muscles and sometimes you cramp.
