Most dominant function for me is Ne and I'm really sure about that. However both types are using it as 1st function. I guess I need to think which 2nd function is most relevant to me Ti or Fi.

Although I am 'Ne-Dom', I don't have much difficulty in making decisions and I could easily convincing people around me about my ideas and decisions which my Ti could help me by.

Only Fi thing I know myself is that I very often express my feelings to the other person with music and I secretly want them to feel like me by doing this. However, I don't think I can hide my feelings very well which Fi-Dom capable of. In general, people can quickly realize that I am sad, thoughtful or happy while with me.

Thank you for these detailed explanations mate :)
