Well, I know nothing about type and stuff, and I've never met you face-to-face, so I should probably shut up. However, allow me to summarize what I've seen and heard from/about you.
You definitely come across as very Se-like. But I've read that introverts show their aux to the world, and their first function is a very deep, personal side. So could it be that you are ISFP, but you always show us your Se side?
I've heard a lot of people comment that your N is well developed. If you were ESFP, that would be highly unlikely, wouldn't it? As I recall, you're in your early 30s, right? So that would mean your tertiary is starting to really come into play, and can we REALLY say that's Te?
Besides, how you come across online can be very different from real life. Only you can really tell if you find interacting with the world around you and acting in the immediate context (not necessarily with people!!!) is exciting or draining for you. Or if you really feel like Se guides you or just helps you out.
What can we conclude? I'm too incompetent to figure it out myself, but those are my impressions. Nothing else other than XSFP - probably a weak i or a weak e.
Besides, we have to be really careful of not treading the slippery slope of folk typology, and rather look at what motivates your thoughts and feelings.
