I just started road cycling last year. I had a nice comfy seat. The first long ride I took was 61 miles. My junk was numb for 2 days. On the advice of some folks here I invested in a good saddle and proper shorts. No troubles since. This year I've completed my first century, a couple 75 milers and numerous rides over 50 miles with no ill effects to my fun sac. That's my experience.
