I think that the sack would be equally painful Keef - all that tugging on your marble pouch. Still, the ladies seem to go through some truly awful procedures on an entirely volunary basis (depilation of a variety of types, plastic surgery, child birth) so we shouldnt complain. Having said that my back, sack and crack are my own private kingdoms and nobody is getting anywhere near them - which is the source of a great deal of regret.
