I briefly dated an older man whose buddies, all married men with children and often grand children went into brothels on golf holidays to Portugal etc.
I hadn't even thought of Portugal as a likely place to have brothels but these guys were clearly highly motivated, this was even before the internet was really in popular use.
They were paying for sex with women young enough to ve their daughters, in some cases granddaughters while their wives thought they were just off golfing with the lads (and probably thought they were well past that sort of interest or behaviour).
Behind it lies utter entitlement, including the "what they don't know won't hurt them" schtick.
The one I was dated was less good at keeping infidelity on the Qt, had more than one affair and was going through a divorce when I dated him. He became really vulgar when drunk , referred to women habitually as bitches, gripped my arm painfully when talking to me (apparently unaware), and having told me he really liked "big knockers" started pointing out women when drunk whose busts he liked a d thought were a good example. He joked about a boob job for me. Through all this he was impotent and claimed it was recent, which I found out was untrue.
The relationship did not last (obviously) but if illustrates exactly what these men are like behind the pc surface.
At least his prostitute in Portugal was lucky - since he couldn't get it up.
