is this the same amputee you had a thread on a long time ago? the one where you talked about how you can achieve much deeper penetration without that other leg in the way? i know a group of people here in dallas who make prosthetic limbs for a living and they usually roll out with the people the have done work for. i have been out with a few girls with a whole prosthetic leg, yet i've never wondered about whether or not i could get better penetration on her sans limb. i must be slow.
