Desperately Craves Affection

In general, it's assumed that we all need affection (physical mostly as well as verbal) to thrive. This is essentially the opposite of Hates Being Touched (or sometimes the person is a combination of this trope and Hates Being Touched) where a person has perhaps been deprived of affection for so long that they desperately crave it. May or may not lead to the person exhibiting No Sense of Personal Space.

Compare Love Hungry, where the character wants to force others to love them.
