Looks like every other review mentions DT. This is what I think of at DT. I have only had one provider come close.
that guys should stop putting DT in their reviews if they didn't actually go all the way.
However, it is a difficult skill to learn and clients should not expect it (unless I guess if you are paying for PSE) and never force it like in those movies.
Here is the provider that you want:

It is a learned skill...and somewhat is just possible or not. Takes some planning too...many variables.
I don't doubt the difficulty or acquired skill associated with it.
Lets just stop calling ever BJ where someone takes it in past the head ad DT BJ...cause it ain't.
I dated a girl for a bit that had no gag reflex...and there is a huge difference.
