This might be a stupid question but I've never experienced this before. Lol. My SO has been sick (head cold). He sweats like you wouldn't believe, but never really STINKS. He's had odd smells before, especially With work. But here lately he has full on STUNK so bad. The past couple days. When he gets up for work, I'll roll over and be partly on his side of the bed, and this morning was bed. I met a face full of RANK. I almost puked.

Could the sweating combined with the sick be why he stinks?? He just showered too. Lol. I don't get it. He's never stunk in the 4 yrs we've been together.
