I have to go with taste. Not really that much of a "foody". My second choice would be smell but a lot of great memories are tied to smell and the rest of the senses listed are essential.
If you lose smell you also lose taste. I would lose taste, I think, even though I would be distraught if I couldn't taste pussy anymore.
Touch.
Doesn't that mean I could more or less get kicked in the balls all day long and not feel a thing?. I mean if I lose my touch feeling, I wouldn't FEEL anything. I'd jump into as many fights as I could and just remain in them untill I won!. I'd be immensly fearsome.
