I guess you could try it. You might do a search on TE for "saddle sore" and see if any other home remedies have been suggested. All I know is that I tried just about everything else, and zit cream worked within 24 hours. For a few dollars, it might be worth getting.
As for shorts, check out Performance.com or Nashbar.com for some good deals. Of course, TE is a great source, too, and is offering a sale right now. A lot of TE's shorts are admittedly on the high end though.
