I'm saying that an 18-20 year-old is going to be kind of insufferable for a man Woody's age. When you're after a piece of ass, it's easy to pretend to be interested in what they are saying and shit.
But after the orgasm, it's just going to be annoying and wreck the whole "good feeling" we were going for as a birthday present.
I figure a 25-year-old is still young enough to be a great score and might actually have some insight into the adult world. So you could stand her company after the deed is done.
Unfortunately in the real world, 18-20 year-olds don't just drop their pants and bend over, then leave once you're finished...altough, a prostitute would.
There you go Woody, find an 18-20 year-old prostitute to celebrate your birthday.
(How creepy is it now?)
