Some useful info here to "clean up" the uncertainty. ..
Lounges...such as Sinsations in Jhb....have purposely built gloryholes....
A raised platrorm where guys stand and display their packages....and a row of cubicles. .in which the "blower" is.... (lockable)
There are adequate facilities to clean those peckers....and quite frankly. ..don't think anyone would present a mouldy member. ..
The access hole is also a large slot....allowing more than just sucking....cupping.. fingering etc
And yes....Women do visit with partners...and both blow.....problem is ...you don't know who's mouth you cum in...lol
Best to stick to legal established places like these though.....cause I once.. ( long ago) saw security guards trying to free a guy.......who's dick had a full toilet roll tied to it with Nylon ties. ( Ziplock straps) at a shopping mall....
