DH is exactly the same, I on the other hand am not allowed to put my feet anywhere near him in bed because they are freezing cold apparently as are my hands. YANBU. But really, where are you planning to stick it??
After years of being too cold - my DP likes a really thin duvet and the window open even in the winter and then prefers the non-window side of the bed (but that's another story) we invested in separate single duvets; his is the equivalent of a sheet. I have a tog 7 and a tog 10. I have been known to use both. I sleep sooo much better when I'm warm. I warmly (sorry) recommend single duvets
I house sat for an AngloDanish couple when duvets were first becoming widely available and popular in the UK. They had two singles on a kingsize bed and when I commented on this they told me that double/kingsize duvets were unheard of in Scandinavia!
I think guests thought it funny that I'd put singles on my wedding list, but for many years I found that was absolutely the way to go. It was only due to "man pressure" that I ever tried a double, and never liked it.
