For saddle sores, make sure your seat height isn't too high. I see so many people with their seats too high, and they have nothing but (Pun intended) problems, saddle sores, pain, etc. THey chase seats rather than fixing the cause, seat height. I had the issue after my bike was set up initially, and I suffered with it for quite some time, until I finally gave in and lowered the seat height to what was right for me, not what a chart, formula, or other "expert" said it should be. After that, seat nirvana, no more issues. I ride as far as I want, with no special bike shorts, with no problems. Brooks B17.
