We suspect this was not due to any real shortage of "domes" (from the context we assume he means wiener covers) in Korea, but rather to hammer the point home that he was getting some, but in a responsible manner. He might have also been embarrassed to ask his mother to send him condoms in with her usual care package of cookies and socks.
Chung apparently took things a little too far when he boasted about how everyone in the industry was kissing his ass:
"...I have bankers calling me everyday with opportunities and they pretty much cater to my every whim - you know (golfing events, lavish dinners, a night out clubbing)"
A night out clubbing? With bankers? Awesome!
We're not sure what was worse, Peter writing the email in the first place, deciding to send said email from his work account or his choice of friends to send the email to. The result was the email being forwarded to a whole lot of people in the investment banking industry.
Within days, Chung was forced to resign in disgrace, probably with a case of crabs to boot. Thus the Sex King of Korea's reign ended shortly after it began, and his plan to f**k every beautiful woman in the country was likely never realized.
