Sounds like trying a new saddle might help a lot. Also, some type of lubrication...Chamois Butt'r or just plain lotion. When I started riding last year, I thought my "hoo hah" would never be the same. I had to wear skirts to work for a week until everything healed. Then I got a Terry Butterfly saddle and started lubing myself up.

This season I've discovered Queen Helene Cocoa Butter lotion...it's super cheap,it works great, smells pretty good, and washes out of my shorts easily. I use A TON. I put it on my chamois and on me. I've also used baby lotions, Astroglide, and Vaseline Intensive Care. Strangely enough, Chamois Butt'r irritates my skin...maybe it's the lanolin? Anyway, lotion would be an easy thing to try out. I tried "mowing the lawn" but that actually made things worse for me.
