Hi Fernando
I am a Danish citicen, and also living in Denmark after some years abroad.
The sex tourism has increased a little in Denmark, but not much(has always been a issue, since the late 60's) . And again mainly in the country-border areas close to Sweden (Copenhagen and Ålborg) and close to Germany (Southern Denmark). As this somehow seems to be kind of exportproduct, though I believe the girls are from Asia, Greenland and Eastern Europe....
Copywatch sellers are by the way also very aggressive in Bangkok say Sukhumvit road. This is also the road were a lot of the nightlife etc is. I used to go there a lot (nowadays less) due to the company I work for always seemed to book a Hotel in the middle of it (having some great Hotel discounts).
I believe the sellers think less tourist=they need to sell more to each individual. This gives a hassle for me as a business traveller getting sick of beeing attacked and insulted by the copysellers. This because i dont by anything from them anyway. But anyway, working fast and looking straight ahead helps
