Yes. _Definitely_ interdental. To varying degrees. Usually it just barely
sticks out, but sometimes (usually for emphasis) up to over a quarter of an

So perhaps instead of [T] and [T-], I should have used [T+] and [T]?
Actually, the later form (postdental) sounds more /s/-like to me than the
interdental form that I use more commonly (which is why I use it in /ts/).

This is very interesting! So there is no single "right way" to do it?

I think I like the later way better. The "apical s" sounds too similar
to /S/ for my taste (or I'm just doing it wrong), and seems a little more
difficult to make. This is probably because I'm used to having the tongue
closer to the teeth. Also, when I try putting my tongue tip behind the
teeth near the alveolar ridge it tends to slip downward. This "laminal s"
doesn't seem to do this as much IMO.

No one's ever told me so, but I believe it probably is (see below).

This sounds very likely to me. I know that when I make an interdental
fricative, I can push quite a bit of air out from between my front teeth
(hence a hissing sound). And I can only think of one childhood memory where
a friend thought I made s's funny. He wanted to make sure, so he asked me
to say "uterus", which was a word I didn't want to say at that age. :) I
had mostly forgotten about that incident until recently, and I certainly
had no incentive to ever experiment with other ways.

I think another big problem, though, is not with my tongue or mouth, but
with my ears and brain. If I were to attempt to pronounce /T/ correctly, it
would sound like an /s/ to me. So if I comment on, for example, the size of
a juicy piece of meat, it will sound to me as if I were saying "That's one
sick* piece of meat!". Obviously, I wouldn't want to say that! To my
ears, /T/ just sounds like it should be an affricate. Wierd, huh?
