Positive Relationship and Instantaneous Personal Magnetism would be a good combinataion
Depending on you, you might also want to consider,
Anxiety Free if you're self conscious about the prospect.
Self-Esteem Supercharger - much easier to be appriecated by someone when you have a sound self-esteem.
Sales Leap - if you get tongue tied.
New History Generator if you've had dissapointing relationships in the past that influence your present thoughtslike, 'I always attract the drunks.'
I'm not saying you need them all. I am saying from an individual persective any and many of the Paraliminals prove useful.
