The sexual act known as the Iron Horse is one for the brave.
You require the following:
- A naked Man
- A naked Woman
- A bed with a headboard / bars
- A decently long hallway
- A helmet

Steps to completion:
The naked man starts at the far end of the decently long hallway, hopefully already fairly excited. The naked woman positions herself on the bed grabbing onto the headboard / bars, on her hands and knees in the doggy-style position. She must also have put on the helmet, and is preferably already somewhat excited. Now, the man at the end of the decently long hallway should begin running down the hallway towards his waiting woman on the bed. At distance (male's judgment), the male jumps into the air screaming "Iron Horse" while attempting to land his wood into the waiting woman's vaginal cavity. Upon a successful completion of this act, the male has indeed landed his wood into the female's vaginal cavity and the female's head has been punched through the headboard as well as the wall behind the bed(should there be a wall there).

(Note: for males who wish to attempt such an act, the following advice is offered. Do not try this while drunk, perhaps your female should be. This is not recommended for the depth-perception impaired or those with otherwise horrible aim. Upon failure of this act, a trip to your local emergency room is strongly suggested.)

The sexual act consisting of 2 men naked, a cup full of shit, and a large dildo. One man shits into a cup while the other man gets into doggy-style position. The man who has now shat in the cup sits on the other man's back, riding him like a horse while holding the cup full of shit over the other man's mouth and nose. The man on top also fucks the bottom guy in the ass with the large dildo, completing the "Iron Horse" This is an example of a dusty poo fetish, and can also be seen at gay orgy's.
