I used to have the same problem. Key solution is "sit like a girl".....I kid you not. Ifound I was sitting down like I always did in pants; bend over at the waist, sweep the pleats, and plunked my rear into the seat....never worked. Always....ahem...."stuff" touched. I watched the tutorial and discussed offline with a very helpful female member. Her suggestion was brilliant. Instead of bending over at the waist, lower yourself into the seat by bending at the knees, sweep, and when your rear hits the seat slide back into the seat. No more problems.
