The term “packing” refers to the process of creating a male-looking and/or male-feeling bulge in one’s crotch. This can be accomplished through a home-made or store-bought pants stuffer, or through a realistic-looking prosthetic device. A packing device may be referred to as a “packer” or “packy,” or as an “STP packer” if it can also be used to pee through while standing up (STP= Stand To Pee). Some guys simply refer to their packer or prosthetic as a cock and balls, a dick, etc.
The goal of packing differs depending on who is doing it. A number of trans men do not pack at all– some find it too hot and/or sticky, others find it uncomfortable and/or inconvenient, and still others find it personally unnecessary. Some trans men pack simply for the sake of creating a realistic-looking bulge in their pants. Others may pack only on certain occasions (while swimming, while in the locker room, or wearing tight-fitting pants). Still others may feel incomplete and/or conspicuous without wearing a packer or prosthetic device. Some have realistic prosthetics that are affixed to the skin for wear throughout the day and night. For many trans men, the term “packing” itself is not even an accurate descriptor for the wearing of a prosthetic device– a prosthetic may be considered an extension of the body rather than merely a pants-stuffer.
To “pack hard” refers to the wearing of a dildo or other prosthetic device that is erect and can be used for sexual penetration. As the vast majority men do not walk around for most of the day with an erect penis, the more common appliances are used for "soft packing,“ or packing with the intent to create the look and/or feel of a flaccid penis and scrotum.
