If you could have your leg amputated, just below the knee... ???
 

And slot it back on, painlessly, when you wanted too, or were not in bed...

Which leg would you choose ?

I'd go left!

You?

If I picked both would I get to shoot my girlfriend?

I'd get the right one cut off, and walk around on my right knee + my dick as the other leg, and use the complete left leg as a penis.

You must have made a lot of money in your day and have a lot of time on your hands to be so bored that you post something like this.
