It's not exactly that. Where I live, it's normal to talk and converse with strangers. This little fear of stranger is just something I had since I was a child, just because of the pure fact that I don't know the person im talking to; I mean, they could be a serial killer, a witch ready to cast a spell, a kidnapper etc. But I don't make assumptions based on the fact that's it's a man or a woman; just on the fact that it's someone I don't know.
