Chamois butter works wonders. My husband always gets a laugh though when I first pull on my shorts because I am just completely disgusted with the cold, wet slimy feel. Yick. However, within a few moments it warms right up and I'm okay. I never thought I'd like the stuff but it keeps things from sticking and I think that helps with the saddle sores.

As for shaved, I've got the 70/90 split I've found if I get lazy and don't shave every day or so, it makes things worse.
