Saddles are a personal thing. The bicycle rider's dilemma, finding a comfortable saddle. Before you write off your current saddle I would spend a little more time with it. We could go into all the variables, but, your complaint is one that most new riders voice. If after a handful of 25 miles rides and it has been correctly adjusted... then you should start looking for a new saddle and our suggestions can address your specific complaint. But remember, what's good for me, is not necessarily going to be good for you or anyone else.
Take a couple of days off the bike and let your butt heal a little.
