I definitely heat up in the evening when laying down. I may need socks + woollen socks through the day, but it's socks off time during the evening movie. And sleeping time means full-body heating, which my partner really appreciates.

With my partner we have complementary heating systems. I get warm in the evening when they are cold, and they warm up after eating which does nothing for me. The difference is radical.

I guess partly due to this I would never spend a day without a shower in the morning. I've never been sick enough to skip a morning shower, even in a high fever (or especially then I guess, due to sweating more than usual). The dirty feeling is just too much to bear.

You feel the sensation of warmth because your body is trying to cool down. It does so by raising the temperature of your skin so more heat is dumped into the environment. This is part of the reason why drinking can lead to hypothermia. https://pubmed.ncbi.nlm.nih.gov/1811578/ “Alcohol is a dominant cause of death in urban hypothermia. Drinking alcohol gives a pleasant feeling of warmth.”

Try taking your core body temperature using a thermometer rather than relying on perceived temperature.

Sounds logical. I don't mind which mechanism is behind it, but the ability to heat up any sleeping spot to a comfortable temperature for two is feature I quite like.
