How does a heteroual male go about getting a trim?

I figure it'd be more appealing to not look like Sasquatch is nesting in my underwear, so I'm wondering how am I supposed to trim my hair down there? I mean, do I go to Procuts, whip out my junk and ask for a "special" haircut? Are there salons that have notebooks with photo samples of private parts with different styles of trim? Do I ask for "The Mankini"? What do I do?
