Apologies for the generalization and I mean no disrespect to anybody. At US nude public beaches observed on many occasions, groups of unaccompanied males in said undies would gawk in mass.

When your thousands of miles from home and family, working weeks on end and your male ...where are you going to go when you get some time off? Again my premises is based on assumption that the Chinese construction firm follows standard SOP of importing their labor.
