Question for the girls only

I'd like to ask some of the girls here a question. Genuinely want to know whether they suffer the same.

Sometimes when I'm at the market or a shop, or somewhere very public, I start panicking around some people.

A few men just really make me uncomfortable even though I don't know them.

Not all, but some actually make me feel scared and I just want to get away from them.

It happens with mostly older men, but some tall, some short. Nothing specific.

I wanted to know exactly what is happening, why, and whether I can control it.

NSFW tag just in case.

Thank you people
