Saddle hurt, saddle sores

I don't see any other chicks commenting on here and lots of gooch talk so I don't know if I'm getting the same saddle sores as you guys are. Basically, I have freaking callouses where my sit bones are. I'm riding double what I did in NYC, yes, but I'm back on a bike that is more to my size - the top tube was too long on the Coventry Eagle. I'm riding the same saddle as in NYC (the last place I did riding this regular, but it was last September when I had to quit).

The only thing I can come up with that is different is I'm not wearing padded shorts. But how do I get rid of the callouses? I'm not going to the salon and have the lady give me a butticure.

If the top tube was longer on your previous bike, it probably moved more of your weight off your arse onto your wrists which might help with arsesoreness, though obviously with corresponding disbenefits in handsoreness. Also, talking of weight, you're pretty slim - maybe some additional pies would help with internal padding?
