Ditto about the "it's going to hurt anyway". Several years ago I did a ride across Arizona & was in the saddle for 9 days @ approx 65 miles/day. At the end, my legs, back, etc., were fine but my "nether bits" (love that!) were screaming. The last two days were really painful.

Now I can say "I did it" and I don't ever have to do it again!
