I wore MX275 on a first date, she was generally relaxed and happy for the evening, no, nothing happened more than a couple of lingering hugs, as it was the first time we met, but by the end of the evening she was already making plans to meet again 
I had on-
1 drop A314 inner arm
1 spray Instant Honesty x4 inner forearm
2 sprays Instant Openness x2 (wrists, back of the neck)
2 sprays MX275 chest and back of the head/neck
2 blots Turn Up The Heat, on collar bones, (turned bottle over on finger, touched collar bone) [right where her nose was when we hugged 
]
(2 sprays, 2 locations means one spray per spot)
Happy, open, slightly nervous, (both of us) meeting cold, but we had chatted online. had a light dinner and talked for ~3 hours.
I have used MX276 a bit, and MX277 once, but not enough to get a feel for them yet.
