Someone brought up the comparison of removing a woman's clitoral hood. I agree that this is something I would not want done. What confuses me is dopple's lack of a frame of reference. You've been without your foreskin since infancy, so how exactly do you know that your lack of sensation is due to the absence of your foreskin? I still have my clitoral hood, and despite that I find that there are periods of time when it is still less sensitive. This is usually following a consistent stint of masturbation or stimulation.
I am an avid horseback rider, and spending hours straddling a giant piece of leather on top of a giant animal will also deaden some feeling on occasion. To combat this, I spend a lot free time in my room naked. One, it simply feels good. Two, it allows my body to breathe and relax properly. We spend most of our days confined and restricted by our clothing. We frequently wear materials that don't allow our skin to breathe properly, making us sweaty and uncomfortable. I am also a fan of non-sexual touching. Our bodies have very strong memories associated with touch. Kind of like muscle memory.
