This may sound crazy, but last year when I got the saddle sore from hell while trying out a Terry Damselfly saddle (never again!), I actually shaved around the area, put on triple antibiotic ointment, and then one of those soft flexible fabric band-aids so I could ride. I never felt the band-aid, and it really seemed to help the sore not bother as much and not get any worse, plus the antibiotic ointment should have kept bacteria at bay. Good luck to your friend; saddle sores are the pits!
