Why do I give off extreme degrees of heat when I'm sleeping?

In the past few years, I have received complaints in multiple relationships that the degree of body heat I give off when I’m sleeping is BOTHERSOME. At one point, one individual jerked up out of bed ANGRY (woke me up in the process), and said that he couldn’t sleep because my body heat was causing him to sweat. The strangest thing is that it doesn’t make ME sweat…and often times, my feet will be like ice at the same time. I can’t even tell that my body is on fire, honestly, and if it didn’t cause people to want to sleep so far away from me, I might not care at all. Anyone have ideas on this?
