sweaty sleepers

Courtney🤘🏻 • I just want to cuddle my boyfriend and pet my cat. 👫🐱
Does anyone else's boyfriends swear a ridiculous amount when they sleep? My boyfriend will actually soak blankets during the night. We sleep with the window open, so it's not like the room is to hot, it's actually pretty chilly. But he still sweats so much. Most nights I actually have to change the blanket cause he gets that sweaty. 
Am I the only one dealing with sweaty boyfriend sleepers?
