I don't think that this is really a problem, I understand what it means and what comes of people being "social", YOu should'nt want to be social, just find some actual good people to talk to.
I get flushed also, I hate that feeling, it goes away though when I realize how awful what Im looking at is. Yep, getting flushed is the wrong thing to feel, you should rather be disgusted, angry, sad, afraid, melancholly, things like that.
Who cares if you over step some delusional retarded boundaries?
If they ain't good people, don't be social with them, that's all that there is to it.
And another thing, don't ever date, it's bad, it's very very bad.
