You know - I am thinking that a good file to propose is one where you can just learn to release your bladder laying down conciously - for me that would be an adequate stopping point and probably much easier to get too. -- This seems to be a big hurdle for a lot of folks to get past.
I REALLY don't want to loose control but do like peeing and think that would be a good intermediate step for those who want to go further down the loose control path or just want to be able to enjoy some variations with wet sex, etc..
A lot of folks simply cannot let go while laying down despite how much they relax.
