Went for a 20 mile bike ride today around Norwich, and I swear to god my arse was in tatters after it, red raw. Let the hilarity ensue.

Only got the bike 3 days ago and I want to change the saddle that came with it.

Are there any seats/saddle designed for comfort in mind? Im off to do a quick google search for bike saddles for fat arses.... Wouldnt say im fat though, but not skinny....
