This has been a fear of mine on-and-off for many years. I fear that I will blush while someone is talking to me at work. Sometimes I can actually feel my cheeks going red, then I become self-conscious about whether the other person will notice, and that makes it even worse.

It only happens when men are speaking to me, particularly ones who are more senior than me. Part of my fear is that if I blush in front of a man, they might think I fancy them (in reality, I'm asexual so I don't get feelings of attraction to anyone, regardless of gender, but I never tell anyone at work about that - in fact only my closest family and friends know about it, so people probably assume I'm heterosexual which is why I only get these fears when men speak to me).

How can I counter/disprove my automatic negative thoughts about blushing in front of men? Is it likely that people notice me blushing? Do men really think that if a girl starts blushing in front of him, it means she fancies him, or am I being totally irrational? This has been a problem for me on and off over the years, but it's the first time it's started happening in my current job.
