Just want to note that a softer/bigger saddle is not always more comfortable while on the bike (or after): Ideally you want your weight to be transmitted from your bones to the bike. Since your bones are inside your body, there has to be some soft tissue involved in the weight transfer. A big, soft seat spreads this out, but often irritates more soft tissue as a result, because the area the weight is distributed to isn't itself good at transmitting force to your pelvis. If you get a seat with the right shape for your skeletal structure and riding position, it can be quite firm while still being very comfortable.
