This question is for anyone with experience.

I have been thinking about freezing multiple loads of cum as I have seen many members do for the sake of covering my wife's face and body like never before! Some questions have come up though:

1) What is the best "container" to cum in and freeze
2) Everytime you add a load, do you pull the container out of the freezer while you jerk off? If so, doesnt it thaw out every time while you "build up"?
3) If above is true, how do you avoid thawing and re-freezing the cum as you add more and more loads?

Thanks a bunch!
