I think that the guys who do this are either infantile, of low education, have blue collar jobs, or are socially unsophisticated. You'd never see someone in business attire making an adjustment in public.

My husband has never done it either thank god. You could be right there moonlight.

OK and this sounds crass but why do some men just "touch it" not adjusting anything just touch it every so often? EEK! We see you, you know.

Yes gross, sorry.
