I use Jason Tea Tree Gel http://vitanetonline.com/description.../Tea-Tree-Gel/
for the red bumps I get in sensitive places....this would be after your shower instead of the astringent you are using now....I find it very soothing and it's made with natural ingredients.

I wax, not shave, and must always plan the wax for at least one full day before a ride of any length.

Hugs and butterflies,
