I want to give one certain woman, and a group of women my hearty thanks.  Those of us in our 60's did our early sexual discoveries before the sexual revolution.  It was our firm male belief that no women really wanted sex, and that we had to pry and wile our way to the promised land.  Then one evening on a bench seat at the drive in, my hand slid down and rubbed her crotch with no opposition.  Dare I?  In an early surge of courage, I unfastened the button of her pants and slid my and slowly inside her panties.  Expecting a slap in the face, and the end of an amorous evening, I braced myself.  Then, wonder of all wonders, her legs parted, allowing my virgin hand to cup her  womanhood, moist, soft, and pulsating.  
Low and behold, she was as desirous as I.  This seems common sense now, but in those days it was a revelation.  So, my hat is off to those ladies, who at that magic moment parted their thighs.  I must admit, low these many years later, I still get a special thrill, slipping my hand down a waistband and cupping that moist delight.
