I have used Passion Copulin Concerntrate perhaps twice a week for over a year. Being unmarried I was hoping that the effect you query MIGHT instigate some competition in potential female mates. I can not say hand on heart there has been much of an effect, like this, or any other from my use of copulins. I have used small up to very large doses.
I do recall that in the women’s forum they, largely (although not entirely), point to the ineffectiveness of men using copulins to attract women. My own experiences would certainly back this up.
Interesting story though; and to answer you in one phrase I would say yes it is entirely possible. Would have been interesting to test further over the course of a few weeks, without her knowing you had copulins on. But now she knows!
