My fiancé sweats every night without fail, it doesn't matter whether it's winter or summer, whether he sleeps with a blanket, duvet or nothing, or if he showers before bed he still sweats. It gets so bad that I can't even cuddle him as he's too sweaty, I have to change the bedding almost every other day as it just smells and feels horrible. I have asked him about it but he doesn't know what causes it, and I feel really bad because he will roll over for a cuddle and I give him a quick squeeze and roll away as I can't stay too close to him for too long as he just sweats on me.
