One of the great things about Gilbert Arenas is that he’s one NBA star not afraid to speak from his heart - or about his loins.

DC SPORTS BOG spies Agent Zero having a quick one-page chat with MEN’S JOURNAL. The mag asked Arenas a few questions, such as his favorite drink (Corona & a Shirley Temple, mixed) and his favorite place on earth (his own backyard, once he has his Playboy-inspired pool put in).

But when quizzed about the worst physical pain he’s experienced, Gilbert gives a cringe-worthy response. Read on, if you dare:

“When I was new in the NBA the team veterans convinced me to shave, you know, down there, because they said the hair stinks. I used my girlfriend’s razor, which was rusty and gave me keloids.”

Ouch. Unfortunately, Gilbert made his cure worse than his injury:

“The doctor prescribed medicine to dab on, but I just poured it all over. Three days later I woke up screaming. The skin was burnt off my scrotum, down to my crack, everything — just raw flesh. I still had to run and play, so I used a numbing spray for a month until it healed.

We repeat - OUCH!

Luckily, Agent Zero learned from his agonizing adventures in groin hygiene:

“Now I use clippers.”

Let that be a valuable lesson. It really is worth the extra $2.50 to pick up a brand new bag of Bic disposables. Do it for yourself. More importantly, do if for your special friend “down there”.
