Hi Susan 
So, for sweet and soft…TAH’s the thing. Go with IS/B as Kitty suggested. MX135/235/335 are also TAH heavy (the same molecules, just different scent packages) and gives a bright, sparkly, center of attention vibe. I’d go with Instant Shine for an uplifting fun to be around vibe…and Instant Openness, to encourage conversation, rather than Honesty to start. Honesty can be intense, unless you’re looking to quickly cut to the chase… better to keep it fun and light first time out, I think. Also, Scent of Eros for women is a great product. It contains copulins and a-nol. (Available at Love Scents) A great combination to impart a sexy, youthful vibe/glow. I’m not going to suggest advanced products at this time…buuuut… you should keep P86 in mind.
One of the best things you can do, to quickly gain some knowledge, is to take time to read the sticky’s at the top of each forum. You may find this thread especially helpful.
Remember to try them individually, at first, starting with one spray. After you find the number of sprays/dose that works best for you (your “sweet spot”) … you’ll have a better understanding of the effects and how to combine them to your advantage.
Hope that helps. I’m looking forward to your adventures, don’t forget to keep us posted!
