I’m a Belgian guy, and I travel all the time. I don’t use CouchSurfing for actually surfing; I use it to meet with locals, especially with very cute female locals 😉
Before going to Korea, I sent out a bunch of emails to some cute girls. I would say a good chunk of them enthusiastically replied.
I ended up sleeping with 3 girls in 5 days I was there. It was like a revolving door. So the moral of the story: if you’re Belgian, then you should go to Korea ;))
