In the pre Aids world bulges abounded. Men wore special "basket" jeans and often sanded the fabric of the crotch where they would place their junk and allowing the cock to be clearly displayed. It wasn't as prominent with the suits, but among the counter culture it was very popular and in gay neighborhoods in was the norm.
Sadly this all vanished as the puritism of the 1990s came to the forefront and profit pleasure began to replace sexual pleasure.
However, the package is definitely back and I too rejoice to see the bulges. My very favorite are basketball shorts without underwear. You not only get to see the bulge, always alluring, but you get a delictable insinuation of the cock itself, it's size, the angle it hangs at, is it the cock head that's making the bulge or is it the length of a good size semi that making the guy tent? Of course with the shiny fabric rubbing on ones dick, they're usually sporting a semi. Yes! Do it!
I live near the NYU campus and it is bulge heaven here, be it well muscled jock or exotic Parsons art student in tight skinny jeans spattered with paint. The only thing I love more than men themselves is what hangs between their legs, especially when the package is attractively presented.
