Only having metaphrical balls
I can not comment on the pain factor I have seen enough male players on the floor / crying to know it really hurts.
Yes it hurts when you get shot in the boobs
if you are vain and silly enough to wear a lyiong wonderbra or such it really hurts.
If you have sence you wear a nice big T Shirt Bra they have a life of their own on the washing line as they have a pre formed cup and I defiy any one to be able to feel anything through one.
I was once lit up aross the boobs in a tourney in frount of a crowd .......they all expected me to leave the field in tears. HARDLY SUPRISING after 5 shots from 3 feet!
But trusty T shirt bra did it's job and I left laughing
