One tip.

I learned this the practical way while travelling through Yunnan.

Wear a motorbike helmet with proper visor covering your whole face. Very funny to see the reactions when you take your helmet off. Especially when in rural area nobody wears a helmet and they must have realised that you were an alien.

Works as well with police officers. First let them talk to you for 5 minutes and then take your helmet off to make them understand that you didn't understand a word they were saying. They let you off 100% of the time.

PS: I never tried this without motorbike. Might be even more effective if you actually don't have a motorbike.

Having lived in several countries for extended periods I learned that the main function of me as foreigner there was to entertain the local population. Ones you accept that position all the stares and sneaky pictures then become a sign of appreciation of your work and being there and life becomes more enjoyable instead of irritating.

Sorry. I missed the part that you dont want to be rentboy.

Maybe gigolo is something for you.
