There’s a whole label (acoro-) that means: “Is someone whose negative experiences with romance has alienated them from Allo-Romanticism” another one is one that relates to being Neurodivergent and that affecting your romantic attraction .
Essentially, I identify with Acororomantic a bit and I don’t think it makes up the entirety of my Aromanticism for others, that may be different and that is entirely fine! Others may feel that past experiences with romance may have brought them to be Aro-spec/Ace-spec, which I don’t believe make them any less Aromantic than anyone else in my opinion.
The amygdala is part of the Limbic System, if the limbic system happened to be messed up emotions could be affected also. As the amygdala controls the flow of certain hormones, such as Fear, agression, rage, and even sexual feelings. If this were damaged, could the emotions for Fear be repressed or less severe?
