I think that's a great question and certainly worth exploring.
By using pheromone colognes that influence a woman's subconscious, is she being manipulated by a man to do things she otherwise would NOT do? To answer this question, we need to explore the conscious, subconscious, and unconscious mind.
The conscious mind holds thoughts, feelings, and material that we are consciously aware of.
The unconscious mind holds desires, emotions, memories, and drives that we are not consciously aware of.
The subconscious mind acts as a filter between the conscious and unconscious, determining what from the unconscious mind makes it through to the conscious (awareness) level.
Human sex pheromones affect the subconscious filter.
To further understand this question, we need to ask the question "Are men consciously manipulated by women?" The answer is yes.
Women wear push up bras to make their breasts look larger and perkier.
They don't really look like that.
Women wear lipstick when their lips aren't that red.
Women wear make up when they really don't look like that.
Women wear stomach, hip, and butt slimmers to make their body look shapelier than it really is.
The list on physical manipulation goes on and on, and these are CONSCIOUS decisions to alter a man's perception of a woman's beauty.
Is any of this ETHICAL? It's hard to see it as being unethical at first because it is so common and accepted.
But women understand that the more sexually attractive they are, the better their chances are of attracting a good-looking man with resources.
Women manipulate every aspect of their physical appearance to better attract men.
Why? Because men are biologically wired to respond to visual stimuli...
for example, a full set of firm breasts.
So a conscious decision is made to manipulate her looks in order to elicit a greater sexual arousal and response from men.
Pheromones affect people on a subconscious level.
The subconscious, again, is our mind's filter between our unconscious biological/genetic drives, and our conscious state of mind.
Pheromones help to allow more of our biological drives through that filter.
So in this case, the desire for sex is allowed through our mind's filter with greater ease.
And, women do desire sex just as much as men do.
The desire for sex is repressed in many women thanks to social and religious conditioning, so pheromones help to "bring to the surface" a desire that is already there.
Pheromone colognes do not remove free will.
They do not remove from a woman her ability to make a conscious.
Pheromone colognes simply bring to the surface desires that are already present in the unconscious mind.
