Montgomery Ward catalogs (underwear section) and the back pages of Mademoiselle (also bra and pantie ads). Ahhh the seventies.
I actually like photography over video when it comes to whacking it. With video there is ZERO imagination. You just sit there and react to the action. But with photos you actually have to use your mind and imagination to have that image come alive and jump all over your junk. LOL
Ahh kids today know nothing!! :D
