While these things shouldn't deter anybody from travelling in Turkey, they certainly prove that there is a specific code of conduct different from any other country that needs to be respected in order to avoid unnecessary problems.
It will take a little bit of travelling in the country first to get used to this different dynamic, so this will be the time to be extra cautious.

What follows is a list of general guidelines for hitchhiking in Turkey. Remember, however, that you cannot fully master the different dynamics of social interaction, especially between members of opposite sexes, until you've been exposed to the inital special attention you'll receive as a foreigner and possibly made some beginning's mistakes. First of all, keep in mind that in Turkey there is widespread prejudice concerning the willingness of Western girls to engage in casual sex with random strangers.
Having said that, the biggest part of problems arise from the different conceptions of flirting in the West and in Turkey. In Turkey, making eye conctact, smiling and accepting compliments can all easily be interpreted as outright flirtateous behaviour. Another thing to watch out for is that Turkish men will test males travelling with a female to see how protective they are of their female companion.
This will always be in a somewhat playful manner, and hardly ever in a threatening way. One very important thing is that a man travelling with a woman should never let her sit next to a man other than himself. Another important point, if one that goes somewhat without saying, is about clothing.
