I've never been the type to be cold all the time, but I've been hot since I was pregnant 6+ years ago.  Particularly when I was pregnant I couldn't get cool enough.  My poor husband suffered as I set the A/C down to 69 over the summer and didn't go lower only because I felt bad about the electric bill.  I don't want it quite that cool inside anymore, but I probably wouldn't complain if it was. :)
