Could it be that your bike isn't fitted correctly, causing you to bear more weight there than you should be?
If you are positive the bike fits you and is adjusted to you correctly, can you change the tilt of the saddle (try both up and down) to make it more comfortable?
Maybe the Selle SMP would be good for you- google selle smp womens to see it.
Maybe if you had a seat with a really narrow nose, like the Vitesse, you could sit like I sometimes do (unintentionally, just caught myself doing it one day, now notice I do it all the time) with everything off to one side of the nose of the saddle.
I had a Selle Italia that had gel on the nose, but it seemed very solid to me- I don't know what the point was. But generally speaking, for longer rides, cushy just makes you hurt more anyway.
Good luck,
