My DH went on a work trip to somewhere quite hot. It got to around 25C so not unmanageable. I noticed on his return he had shaved down under. This is very unusual for him. When I asked him about it he said he did it because he was so hot and he gets sweaty. It didn't really sit well with me but I've never mentioned it again. He doesn't shave normally here in the summer. Am I thinking too much into this? Also when chatting about this trip on one occasion he became very flushed, red faced and very hot which has never happened before. I felt alarmed by this but have said nothing.
