When we talk about instincts, we refer to those impulses we have when we receive some kind of stimulation, and depending on the stimulus, we react, often without realizing it, such as when we see someone we like and are sexually attracted to. Immediately, our gaze turns to that person, our smile widens, and sometimes we have these reactions without realizing it, until someone else says something like, “You're beaming,” or “Watch out for that smitten smile,” ha ha ha, it happens a lot. There is also a lot of talk about maternal instinct, that feeling you get when you hold your children in your arms for the first time, that desire to protect them that arises without explanation. It is love, just feeling that new being inside us and even more so when we have them in front of us.
