I used to blush All the time. . . I guess for me, the solution was to just roll with it. . . to accept that it was going to happen, and keep moving, and eventually it stopped happening as much.
So basically, if I was somewhere with people, and blushed, I'd just keep acting like I'd been acting. . . and if someone asked me if I had, I'd say, "yeah, I just blushed. and?" and maybe "I blush all the time." and then. . just keep acting like I'd been acting.
The key is, in a lot of ways, to accept yourself how you are-- to change only towards your own goals, not towards somebody else's. When I was in high school, I wanted so desperately to fit in, and I tried so hard, and worried about it all the time, but there was simply no way it was Ever going to happen. I was sometimes reserved, but not shy. In the time since then, a suprising number of people I knew have told me they totally wished they could have been like me, because I didn't seem to care what people thought. . . even though, to me, I was incredibly awkward. . . even though I was the kid who giggled and blushed, couldn't carry a non-intellectual conversation or have normal physical boundaries or know what to wear or say or do to not stick out like. . . well, like someone from another planet.
Remember, it's not what you can do, it's what they think you can do. . . and remember also, that NT's tend to be sheep; they'll often follow as a social norm the example set by the person with the most confidence.
Good luck.
