Try wearing them in place where you do not know the girls. Quite often people that know us already have their minds made up about who we are and our place in their world. You have some great stuff that should be working even with people you know. Perhaps you powers of observation need honing. One of the best ways to do this happens when we are learning the correct doseage for us, we gradually up the dose over the period of a week to a month and we learn how to bserve in different ways as a consequence of dosing experiments. Its part of the fun actully. Do some reading or youtubes on body language. Changes in body language can be observed in face, chest arms, below waist legs and hips. Most of us start with watching eyes and hair, not all the signals are attraction. We need to be able to read disgust for an overdose and deception for starters.
