I was snipped at birth, so there's no way for me to weigh-in on whether or not I'm more 'sensitive' than anyone else!
I suppose I would have to support the idea that it probably is at least a little more 'hygenic', or at least it's easier to clean and/or maintain. I remember being a teenager and having a chat with some mates about it; I'd never heard any stories about 'dick cheese' before then, and hearing them sure made me glad I was indeed circumsized, since having no foreskin means that I don't get any build-up of that nasty stuff! One good friend was telling me that his father had instructed him and his brother to roll the skin back and give it a good wash 2 times per-day, just to keep everything in order! Glad I've got a 'lad' that's more 'low-maintenence'!
