Welcome to pherotalk Chemy,
I totally think for attraction the instant sexiness but since you seem to have that stand off ish vibe I would definitely get the instant shine to give of that warm, jubilant and youthful vibe that attracts others
Yes, the sexiness with the shine is a good idea but read the thread in my signature introducing you to mones so you get a better idea as to what you are dealing with and why I recommended these two.
