I know I shouldn't be looking but a lot of guys at my gym have trimmed pubes. I trim mine as well. It just looks cleaner and feels more hygenic.
Just don't come up over another guy's shoulder and say, "Squared edges huh? I always went for a rounded look... But yours is very contemporary." Some girls at my school gave a hilarious expression to male body-hair clipping - they call it "manscaping." Rather funny. I can see it now, in several years they'll have manscaping salons where guys can chew gum and gossip with each other while they get their pubes trimmed.
