Not necessarily. Sometimes they just passively absorb and return it, some other times they want to control it and try to make people feel what they believe is right to feel.
Fe doesn't really want a "reward", ideally it wants to establish a feedback loop where they give out, you return, they give out again and you just keep making each other happy/validating each other. It's neither selfish nor selfless in its most ideal form, however in reality it ends up that they give out much more than what they receive and they arrive at the point where they start resenting people for being "ungrateful". At worst they secretly hate everyone and become more selfish while still keeping the Fe up, while the shadow Fi and inferior Ti are seething and ready to hit when you least expect it.
The biggest misunderstanding of Fe is thinking they are trying to accomplish something Fi-related and they happen to be more competent, but actually Fe is all about establishing this loop. Some Fi gets caught in the mix because otherwise they wouldn't be able to understand what they personally believe in, but this has either to produce some good Fe results, or it will be discarded in favor of Fe. Si/Ni help them seeing beyond the immediate external stimuli, with Si trying to reference known impressions and Ni trying to guess based on the general trend.
