Neck kissing.... TOP of my list. Front - sides - back.  And a little action around my ears can turn the heat up too. :wink: 
KISSING! ... And LOTS of it! I love someone that knows how to kiss  with varying intensity. Soft ...then passionately. Alternating back and forth. The feel of a set of lips brushing softly across mine can make me boil. 
 
 
Someone that loves to play with my hair.  Brushing it - running their fingers through it, etc.
