Translation of masturbation in German

We returned to the former capital of the South at dawn and were dropped next to our place. We had a very nice day all in all, although it was very touristy. We felt that we have seen enough of the area.
In the autumn of 2006 we flew to South East Asia in order to travel in the region for three weeks. Our first stop was Bangkok airport, where we arrived in the middle of the night, around 4a.m.
We spent a few hours around Plaza de Armas, the main square of the town, eating, shopping and sightseeing. A hassling boy tried to sell us some Peruvian chocolate for one Peso.
