I second all of the things that Ang said about English Bulldogs.
HOWEVER...
Have you considered an AMERICAN bulldog? I had an American bully X, and my cousin has a purebred American bully, and I can tell you...THEY ARE CUDDLERS! My boy Bo was the single most cuddly dog I have EVER met. He slept with me under the covers EVERY night, cuddled on the couch, wanted to be with me always. However, something that you might want to think about if you consider any bully breed...
Cuddling can be sort of a way that a dog takes "ownership" of you. This isn't really a big deal with say...goldens or labs, but with a bully breed you really want to make sure that YOU have control of the situation. For example, allow the cuddling, but only when YOU (or your wife) invite the dog into the bed or onto the couch. Bully breeds can be very strong-willed and need a confident, firm owner. They're not necessarily for the first-time dog owner. Also, they have a TON of energy and will need more than just cuddling! They need frequent, brisk exercise. Good walks, swimming, catch, etc. Our boy Bo had to go to the beach twice a day and swim for an hour solid both times or he would be a nut-job. (running around the house, bugging you, just hyper!) However, if they get a reasonable amount of exercise, they're big ol' lumps in the house and will cuddle you to death.
I highly recommend American bulldogs, as long as you are completely aware of what you're getting into. They are one of my all-time favorite breeds and are clownish, funny and very smart. They're loyal and protective and if properly socialized, a great all-around family dog.
Good luck with your search and I'm glad to see that you're asking questions...ju st look into more than the cuddle factor with any breed, and you'll be fine!
