I think some people suffer more of this for sure but
- good saddle
- a lot of time on saddle
- standing up once in a while even if you don't have to to relieve pressure
these help a lot.
also not related but remembering to have a relaxed upper body and lifting yourself from your core instead of putting all the weight on your hands / wrists / shoulders. these will go a long way on a century ride.
