Years ago I rode in the back of a sports car (which really didn't have a back seat) for about an hour on the highway.
When I got out my buddy had to actually support me from falling down (stone cold sober), cause my body went numb from about my navel all the way down to my feet.
Ever had pins and needles on that much of your body!? My dick and nuts felt SOOOOO weird as I started to get the feeling back (hence the pins and needles). It took about 10 minutes before I could stand and about 15 before I could walk.
Fuck! Even my anus got pins and needles, the whole time I felt like I might have pissed and shit myself, but I wasn't quite sure.
