Ahh time for a little Mason...
No person or situation is the same, some things work for certain people etc. However, having just given some advice to a friend of mine I will pass on what I said to him here.
Its a similar situation in a sense because this girl is younger than him and an advancement on his behalf might be taken the wrong way and result in some sort of debacle but I digress...one must understand the culture and background and generation I am in and from but I think it can work anywhere. He is black and she is I think puerto rican I can't recall...
I told him to look at her and say "that's me"...kind of look her up and down maybe subtly, giving a slight indication of what you know is going to be yours without being obvious about it. She'll say, "whats you?" Just shake your head and say "that's me". Say it as if it is or is going to be Fact, yet nonchalantly or matter of factly as if it is no surprise to you. If she asks again say don't worry about it and continue on with your business. Maybe a day or two later let her know again, "that's me..." Its the first steps of basic flirting beyond a generic friendship. Touching is nice, but might scare some off if they aren't used to it from you. However, if a girl sees a bit of your attitude and starts to wonder what on her could possibly be yours she may start to think...Its not an immediate measurable reaction from her as touching or putting a move on her (if she touches back etc and reciprocates thats a positive indicator) rather its a more subtle approach with an edge.
What your basically doing is staking your claim and calling dibs on the places that make a woman feel the most pleasurable, it can be the pussy, the ass, the titties, or the heart. It also allows her time to reconsider your friendship actually becoming something more, not as much shock value as a touch or kiss, yet shocking enough because she has probably NEVER had someone approach her in such a Masonic way.
thats me...
