Buy her a cherry soda.
In my day, we didn’t use fancy aphrodisiacs. Why, all we needed was a stiff drink and some free Internet porn!
[muttering]Kids these days…[/muttering]
Let’s see…
Soda already has caffine and sugar.
The caffine keeps you awake.
The sugar give you energy.
So with the addition of an aphrodesiac, it will keep you awake, give you energy to go all night ALL WHILE you have the urge to go at it.
I suppose the only other thing to add would be Viagra so us guys could actually go at it all night…
now THAT’S what I call a stiff drink!
What? 
Well… I really killed this thread.
meh. it could be worse.
you could give dimensions on your penis…in another thread in this very forum.
