Salvador, I think the Russian women are not scared to meet the foreign men as in Russia so in another countries, and they are ready to go to there themselves even. But they are afraid of to do whatever wrong first.. That's why they do worry what dress to wear on for first meeting, what kind of hairstyle to make to fascinate a man, where to go to showing the town to foreign man for first time, where to settle him to.... Well, the usual female anxiety and trials..
But of course, they are mostly afraid of meeting at foreign countries, because the English language is not our home language, and sometime it takes a time to understand the situation alright and what to do then if they are in bad or dangerous situation abroad.. but a man doesn't think the same.. Then the woman has to think herself to come back home to Russia.. And this is not a pleasant situation for her, although the bad experience is a good experience too, if all is finished as well..
This is just my opinion on your question.
