Warm lemonade or cold tea?

Lilly, am I right that our body temperature is at about 37°C?
Yes, unless you have a fever.
Should everything with a lower temperature not feel colder then?
Well, it does. However, we still feel differences in the same room. If you touch a wooden cupboard, for example, it seems to have a different temperature than the metal door knob. It must be something about the material.
I once read that different materials have different heat transport abilities.
So you're saying that the wooden cupboard and the metal door knob do indeed have the same temperature just the energy transport works differently?
What do you think?
[a] Lilly and Fred are right. It depends on the different thermal conductive properties of the two materials. Because of the higher thermal conductivity the door knob feels colder.
[b] Lilly and Fred are wrong. Some materials are just colder than others. The thermal conductivity does not play a role.
[c] Lilly and Fred are right. The temperatures of the cupboard and the door knob are different.
