I don't know that there is an answer for this question but maybe someone out there has some coping techniques. I am hot natured in general and I can put off some perspiration. Add a similarly hot-natured cuddle buddy and it can make for some uncomfortable and damp cuddle sessions especially in warmer months. lol
Of course, body heat can be managed, in part, with clothing choices but there is a limit to how much you can take off and follow the rules. In a hotel room, the situation can be a bit easier to manage because you can crank down the air provided both parties are willing, but what do you do if one person is not as hot-natured, or if you are a guest and the room is hot? Do you ask the person to turn on the air? Do you address this in advance of the cuddle? Also, are there cuddle positions that are more "cooling"? Any other coping techniques so you don't wind up a sweaty mess?
PS, I do promote and participate in excellent hygiene and odor control, btw!
