Well my GSD sadly isn't cuddly. Since I'm a very tactile person, that's not easy. We compromise, he tolerates my hugs and I respect his space the rest of the time.
As to the bed, it could be a couple of things. 1. Your dog isn't cuddly right now, but as it matures it may become more so. Varik didn't want ANY affection (too busy) until he was at least 6 months old. Even then--and now--he usually only solicits butt scratches. 2. Your dog doesn't care for it and won't ever really enjoy it. 3. It's too hot for cuddling. I know my GSD gets warm easily and often shifts from spot to spot.
