Welcome to the forums,
for you i would recommend Instant Openness, that is definitely the ice breaker pheromone for sure.
you are right about Instant Shine, that will raise the feel good vibe for everyone as well as yourself (my fave of the social mones)
Instant sexiness A and B will attract, they both have slightly different effects in terms of you will be perceived.
You will probably need a couple of products, not just one so try the to go bottles.
and read the following link
It will tell you exactly what they do
Good luck
