I think both Fi and Fe would be sensitive to negativity, but it may be different types of negativity that affect each one differently.2. Individuals whose primary and secondary functions are Fe process readily the emotions of the external world. For this reason they are very possibly the most likely people to internalize emotional negativity. Ironically enough, this thread that often disses Fe as false, deceptive, hurtful, etc., has some potential to be a prime example of hurtful and/or false Fe. It is possible that a strongly Fe person is going to be the most sensitive to the outside world of negativity, including a thread like this. People are tough also, but this is an angle that i don't believe has been considered, so it seemed worth airing it out.
Going back the birthday analogy...
Thinking about some Fe friends I know, they knew I didnt care for normal cake, but knew I liked coffee and cheesecake, so for one of my birthdays they bought me a coffee cheesecake (which was quite good).
I think both an Fe and a Fi will want to learn someones preferences and give a gift in accordance with those preferences. The difference comes in that Fes would rather honor a specific day and as someone who is more Fi I'd rather give a surprise gift when I thought it might make a difference to someone. For a few special friends I may give a birthday card or even gift but adding some originality to either the gift or its presentation is important to me (it might also be to Fes too I dunno).
I think Fi and Fe want to express very similar things, but Fi wants to find their own way to do it, and Fe wants to do it within the structure of social norms.
I'm sure this book is probably familiar to some of you, but maybe not to everyone, so I'd like to add descriptions from "Was That Really Me?" that pertain to Fi and Fe as dominant function types (not on the actual functions, but on the types that use these as their dominant function, but unlike type specific descriptions, these focus on things common to that function when it is used in the dominant role).
Both of these examples focus on the positives and these only apply to types that use these as dominant functions so it does not cover much as far as auxiliary processes.

Important features of Dominant Introverted Feeling
Introverted feeling types are flexible, open, complicated, mild, modest, and often self-effacing. Though difficult to get to know, they are seen as trustworthy confidants who are tolerant of a wide range of differences. Their habitual approach to people is nonjudgmental, understanding and forgiving. They place a high value on affirming both their own and others individuality and uniqueness. They seek to affirm all parties in a controversy and thus readily see the validity of contradictory points of view. Underlying their characteristic tolerance is an overarching natural curiosity. They find the diversity in the world immensely appealing. ISFPs want to experience as much of the environment, especially the natural environment as possible; INFPs’ desire for broad experience, especially human experience may be secondary to their need to understand it.
Both introverted feeling types may find it difficult to take a firm stance on issues that are not centrally important to them. As a result, they may see themselves and be seen by others as indecisive and lacking in conviction. In matters which they hold strong values, however, they are firm and uncompromising in expressing and enacting their beliefs.
Introverted feeling types focus on what is good in others, so they tend to downplay others’ faults, often forgiving them for slights or minor hurtful behavior. At their best, they accept their own mistakes and imperfections as well, achieving some success in maintaining the inner harmony that Is so important to them.
In crisis situations, they typically will hold back to see if others will solve the problem competently. They are then content to follow someone else’s lead. But if adequate leadership is absent, ISFPs and INFPs may assume a dominant role, acting swiftly, confidently, and competently to handle the situation.From "Was That Realy Me" by Naomi L. Quenk (p. 146)
Important features of Dominant Extraverted Feeling
Extraverted Feeling types typically radiate goodwill and enthusiasm. They are optimistic about life in general, and human potentil in particular. They prefer to focus on the positive, harmonious, and uplifting aspects of people and human relations, paying little attention to negative, pessimistic, limiting and divisive messages, situations, and conclusions. Thier primary goal is to create and maintain good feeling and harmony among people.
Although ESFJs and ENFJs may recognize judgments that rely heavily on logical analysis, cause-and-effect relationships, and statistical odds, they largly ignore such factors in making decisions. Others may therefore see these types as making decisions that "fly in the face of logic." Thinking types may be particularly puzzled and frustrated when an Extraverted Feeling type accurately describes the logical conclusions warrented by a situation but decides in favor of harmony and caring. From a thinking point of view, using such a criterion in decision making is inappropriate.
Extraverted Feeling types are careful not to hurt others' feelings and try to take others' well-being into account. If they cannot avoid telling someone an unpleasant truth, they will carefully soften the message by putting it in an affirmative context. Unconditional positive regard is a strongly held value.
As a result of their natural pleasure in pleasing others, Extraverted Feeling types can mistakenly be seen as overly caring or even codependent. In reality, attending to others' needs is usually a satisfying, legitimate way of expressing their dominant Feeling preference.
In a crisis that does not activate their inferior function, ESFJs and ENFJs focus on alleviating the concerns and suffering of others. They are comfortable letting others manage the more technical aspect of a crisis so they can devote their energies to creating a cooperative, comfortable atmosphere for crisis victims. When a situation demands more forceful methods, however, they will take any action necessaty for the benefit of others.
