There are local guys just hanging out (I'm into 20s / early 30s but there were others) and walking around.
The ones that approached me were usually looking to be a guide (so they get a cut of anything you buy) If you like the look of them, play along and they'll usually offer you themselves.
One took me to his apartment after checking his wife was at work and sneaking me in the side entrance. It was about an hour all in. Good looking, average sized but a very pleasant experience.
Another one I took up, still stayed with his family so he arranged short term accommodation (that i paid for) and I asked I pick up some local beer too. We spent a few hours in apartment together. He was fairly rough but extremely girthy and did whatever I wanted.
