The reason is simple....
How many Turkish girls have you seen working in touristic places? In bars...restaurants... hotels...
And when you look at the gender-composition of the tourist, you´ll also see a LARGE number of females 
I have a bit ´behind the scenes´ knowledge on the whole Turkish boys-tourist girls relationships. Loads of boys are doing this as part of their business. Their bosses push them to flirt with the girls. Loads of times girls walk around in large groups, or are with families. The girls tell the group they´re with that they want to see Ahmet/Ozzy/Ali again, so the whole group goes back to the bar/restaurant where he works. And...spends a lot of money there. Sad situation, but it´s true.
I´m not saying every Turkish boy-foreign girl relationship is something that the Turkish boy pushed for because of business, but it is the large majority of the relationships. And the other relationships are just a matter of people being meeting eachother, which is difficult for the Turkish girls since they are simple not there.
What you say is very true, i don´t doubt it for one second. Its such a shame so many silly girls fall for these men. They dont understand its part of their job.
If he SHOWS you that he loves you, he might just be as in love as he says he is
