Extraverted Sensing is an extraverted and perceiving function. Se deals primarily with experiencing and perceiving the outisde world in the present moment. Se users are in tune with their external environment and take in information from it using their 5 senses. Se users often act on instincts based on information they subconsciously took in from their environment. Se users tend to spot details that others miss. Se is focused on the present, while Si can be more past-oriented.
I found this here: Extraverted Sensing occurs when a person is primarily aware of the external world and all its details. They act on present experience and concrete data to produce the desired results. A person with this preference is able to isolate the relevant facts from the sea of data around them, and they continue seeking more and more information until they have either grasped the whole picture or their circumstances have changed and their attention is directed elsewhere.
People with high Se (dominant or auxiliary) tend to enjoy new experiences that will stimulate their senses. High Se users also tend to have an eye for aesthetics and tend to enjoy the "finer things in life". Se users might find themselves bored by routine, unlike Si users, who tend to find comfort in routine.
Se users also tend to be kinesthetic or visual learners. I found this here: "I like to get my hands on something and really experience and handle it in order to understand it. Written instructions bore me because I prefer to “do” to learn. I tend to be a kinesthetic or visual learner."
