What pheromones can and can't do: realistic expectations for newcomers
Causing something is done by your behavior not by phenomonal influence. Pheromones work on the subconscious to induce feelings.
If you use mones and they arouse someones interest that act of arousal is not what makes him/her have sex. Its the behavoir leading up to that moment that will do this. Mones make you feel more. Your behavior is still controlled by your conscious mind.
