They will at least subconsciously tune into you as the source of the pheromones. However, you will need to interact socially in order for them to stay attracted to you.
Take your example. You are with friends and meet a couple girls. the girls will tune into you as the source of the pheromones. However, if you do not toalk to them or act uninterested, then they will focus on the guys who do talk to them and act interested in them.
The pheromones give you an edge. But people will tell you socially it is 90% you and 10% pheromones. You can’t just sit there like a log and expect everything to happen.
This is a link to a recent post where northwestmichael “rode” his pherowave: My freekin wacky work related BOWLING PARTY EPISODE!
He did not wait for the pheros to have an effect, he went out, did his thing taking advantage of the extra push the pheros gave him. If I go with a high dose of 'none I feel a little more aggressive sometimes. But I turn that into positive action - more outgoing, the “cocky/funny” you read about in some posts here - knowing the pheromones are working in the background.
Same thing with work. I just go about doing what I need to do knowing that the A314 is there backing me up. And because I know the pheromones are there backing me up I know I can push the envelope just that much more.
