Definition - What does Packing mean?
Packing is the practice of wearing a phallic object or padding in the crotch area to mimic the appearance of a penis. It is done by trangendered men, crossdressing women, or women into role playing. Packing may even involve mimicking the appearance of the testicles and scrotum. Packers often pack under clothing that is associated with men.
Kinkly explains Packing
A woman may pack soft or pack hard. Soft packing means that the material used in packing cannot be used for sex or penetration. This may involve soft non-erect dildos, gel-filled condoms, or rolled up socks. Packing hard involves using firm dildos that can be used for penetration. These dildos can be bent underneath the clothing while not in use.
