Tisha has it right - a young guy like you should start with one spray of Ammo. Three might be an OD.
And adding Instant shine to it will only help.
And you are right too. Most younger guys overlook the huge edge that social products like IO, IH, CTTM2 and Instant Shine give you. Ammo is a great product and if she is looking for someone that night the 'none in it will signal to her that you may well be who she is looking for.
But if she is just out with friends and really only wants to meet people, then the social prducts give you a huge edge because they make people happy to be around you and help generate conversations so she gets to know you.
Remember - women equate good, deep conversations to “ggod” people who are caring. That creates the environment for affection to grow and if she feels a lot of affection for you, well then.
