The idea of applying artificial male pheromones to oneself to enhance sexual attractiveness has been around for about 25 years. First, I'm not sure these products really work at all.
Second, is there really such a thing as a "gay" pheromone? What has been marketed for a long time is a MALE pheromone, meant to attract females.
If studies done in Sweden on the topic of pheromones are correct, both straight women AND gay men can be attracted to a naturally-occurring male pheromone. These studies tend to support the theory that being gay is genetically based, since the essentially subconscious response to an olfactory sensation cannot be a matter of willful choice.
There are no separate gay or lesbian pheromones. What is different is that gay men are attracted to a male scent, just like straight women are, whereas straight men are attracted to a female scent.
So there are only 2 human pheromone scents: male & female. If you're gay, and some guy is exuding a male scent, you may be subconsciously attracted to him. So that I suspect these so-called "gay" pheromones are in fact ordinary male pheromones, that have been around for about 25 years.
I wonder if this product is more expensive that the same over-the-counter stuff marketed to straight guys?
