I know your pain! I just got an Oceanic Flex drysuit and love it except for the squeezing part. The jump suit padding really helps. I really dont think briefs or boxers makes a difference though, I wear boxer briefs and it still hurt! I am going to take a drysuit class soon because this is my first drysuit and I am having a hard time with the boyancy part. Was checking the suit for leaks in the legs and got stuck upside down in the pool.
