Your 5 senses

I'd give up smell... because it's the one that I need the least during sex.

reminds me...I heard some where....that smelly feet and b.o. is an aphrodisiac in some cultures (lol)

without touch you'd be unable to eat, walk, have sex, grip stuff properly, prevent injury (burns, biting your tongue etc) and to top it all you'd probably be incontinent. I think i'd make that the last one to lose
