I can't pinpont an exact moment or scene, but it was definitely from watching porn in the late 80s. I am 46 now. I was then just getting into curiosity about sex as I hit the right age, and would constant find my dads porn, of friends dads, big brothers, etc. I think facial shots then were much more rare, but i just instantly fell in love with the way it looked and found it so arousing. Peter North certainly would have been in many of those great scenes that got me hooked.
