Hi Cathleen, welcome to TE
What Grog said... lots of discussion on the boards here

Cornflour, or a cornflour based talcom powder, is great for a rash after you have a shower too...

Angela, just look for a pair of shorts with a quality, thick chamois in it... best to go and actually look in your LBS if you can and then you know what you are looking for and comparing with.
If there is a woman in your LBS, she will prolly have some recommendations...
