"It's Just a whore why do I need to scrub up?"
I think that's the mentality of some folks, Or at least the ones who know they're not fresh and likely to be harvesting abit cheese & BO since their shower in the morning.
I've mentioned it before on here, most WG always make a beeline with the wet wipes behind my foreskin and are met with utter shock when they inspect the wet wipe and don't find anything mucky, I'm guessing some punters are generally clean but aren't 100% thorough.
As for WG's and hygiene, you usually get what you pay for. If they're cheap and in demand don't expect them to shower between punters.
