You have asked for, and received some good advice. Cotton underwear and a gel saddle are not your friends. Cycling shorts are best, and not because of the padding, but because of the wicking properties of the chamois, and the lack of seams where they can chafe. Cotton is bad because in hot weather, the cotton will quickly become soaked with sweat, which will chafe. And the seams will make the problems worse.
And in general, a firm saddle should be more comfortable than a squishy one, provided your butt is acclimated to riding and the saddle fits your sit bones. This applies more to a heavier rider than it would to a lighter rider. Take it FWIW. Get back to us with an update when you find a solution that works.
