Blushing problem

I grew up extremely socially anxious, and while I have gotten much more used to talking to people, I can still be fairly shy. I still blush when people I am not used to talk to me directly, or talk about me, especially males (but it doesn't mean I am attracted to them-- I will blush around any man of any age-- I have always been a girls' girl and I think I just never got used to men talking to me). I think looking people in the eyes especially trips me up. When I was little, I would always look at the ground and avoid speaking. 

I am mostly concerned that people are going to get the wrong impression and think that I am blushing because I am attracted to them or something. 😕 I find that at work, this is particularly bothering me. 

Do you think other people notice my blushing? I feel a little silly asking, but I am curious. 😅 Is there any way to prevent it? It seems to be a knee-jerk reaction that just happens.
