Welcome to the Board!!
I don't do anything - matter of fact in the winter I don't shave anything but my pits! (shhhhh its just our secret!) My question to you would be - is it a question of saddle soreness more than hair related?? there are threads all Over here that deal with both as Irulan said and most of the issue seems to be saddle soreness/break in.
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
