My dad gave me some great advice before he passed away.
He said "If you would't stick your tongue in it, don't stick your dick in it."
Words of wisdom right there.
It's fucking terrible advice because 95% of cunts are rank.
My Uncle John gave me better advice when I was 17... "turn them upside down, they're all the same". It has served me well and hence; I'll stick my dick in it OP.
