The "in" 'do for gay boys across Europe (as seen by English boys, German, Austrian at least), is the close crop on the sides, and quite long on top. Either shaggy as Christian sports, or coiffed up as the below drawing shows, or plastered back a la the 1920s.
Speaking of the fellow below, he was interesting. Maybe 20 years old, 6'2" with a 27" waist, tight T-neck, and pants that when the light hit them just right you realized they were vinyl tight-mesh jeans. Best of all, the sparking bedazzled trainers. Xavier dubbed him "the Dazzler."
Next night we saw a fellow in all-white, who Xavier said, "he looks like the scientist from [Back] to the Future." I said, "oh, Doc Brown." But then it hit me as I drew this, if he had the 'stache, he'd totally be Mark Twain.
Too late in the trip did Christian explain how to order beer in München. The standard is to order "a beer" to produce a half-liter of Augustiner, the standard beer in town. It's light enough to take on several half-liters. But Xavier had been ordering us "white beer" which produces a half liter of something not very white or very light and not easy to finish even one half liter with a heavy German meal.
