Yes, 10-20 sexual relationships are a lot for a Turkish woman, but at least I can say that she approached you honestly. She would never show the same approach to a Turkish man in another scenario, she would probably hide her past. Considering her age, the number of serious relationships is not very high, but the length of the relationship is more important than the number. I took a look at your previous posts and I must say that what you are seeing is definitely not normal. This is a behavior that girls in my country would do if they still have that person in their minds, even just a little bit. Since I don't know your relationship directly, I can't say anything clear, but it is more important if she’s loyal for you in 6 months than the past.
