In the same vein as hymens halfway down a vagina, what is the truth about ball squeezing during intercourse.
It seems to be something of a SOL sex story trope that ball squeezing precipitates a particularly strong and voluminous ejaculation. However I've also seen it recommended, along with the more common squeezing of the base of the penis, as a way of dampening arousal to thwart premature ejaculation.
For some strange reason, this is one case where I don't feel inclined to experiment on myself. So what are the facts?
