I have heard from several that they can not release their yummy juices with a bag on. Is this a mental thing or strangulation from having the bag too tight? The young man from an adult toy store said if you are going to explode your are going to explode, it has nothing to do with the bag.
Maybe its just the preference of drenching the female body with your juices - the erotic warmth and visual sight that is the preference instead of releasing into a container......???
Put it where you want it - just let me know because I just want to make you happy :=)
