I am a blusher and it can be mortifying and have watched a few youtube videos on this, but the cruel way to get over it, is to not care about blushing and as yet, I am not there, especially when people think it vastly amusing to point out: wow, you are red, aren't you?
So, it really does start with us and ends with us. If you can talk your mind around to not caring and seeing it as unique and I hear many chaps finding it most becoming, then the blushing will suddenly calm down. How nasty is that?!
