I believe the term is "hornier than a billy goat with two peckers."
Having tread the Earth for nearly 6 decades, I sometimes find myself in teenage mode. The last week or so, all I think about is sex, porn, providers and masturbating (sometimes all at once ... which is overloading and frying my brain cells).
Whenever I'm out my eyes are always roaming. When I lock on a woman who is anywhere near attractive I immediately check list her - hair, eyes, smile (if I can tell), face, body, how she's dressed. Yes, I tend to stare (sue me.)
My search for the perfect whack off material (written or video) is never ending because I tend to skew toward more bizarre/fantasy type stuff (3d vids particularly draws my attention). God bless Al Gore for inventing the Internet, LOL.
Just my thoughts on a Saturday when I would like to be alone and jacking off.
