See.....these colognes will totally get you some doggy style!!
On a serious note, with the sprays I spray once on a wrist and rub the wrists together, then another on my pulse point on my neck.
With the small non spray types, I put my finger over the top, turn it over to wet my finger and apply to the wrist, at the end of the bicep, the neck pulse point and behind the ear. It sounds like a lot, but its not. The Sprays put out more than the method I just described in 1 spray I believe.
