i agree with shuri 100%. you can basically see the sex friction of 70s stuff, whereas today most porn looks more like pure business than a passionate skill. i prefer porn that looks real, and what's realer than hairy, unattractive men fucking hairy above average women who are actually having fun. there are soooo many hot chicks doing porn today but it's obvious they aren't having fun, and they don't even pretend to.
i know my fellow porn connoisseur Smooth Groove disagrees, but i LOVE gianna michaels. she may not be good looking but she puts everything into her scenes. she has fun, is convincing, and even tries to make the guns cum before they're supposed to - not because she wants the scene to end but because she enjoys the challenge. that's what i like in my porn.
