More than hormonal physiological effects, isn't psychological conditioning a much more dominant factor in consciously self-aware/acknowledged sexual desire? (Especially when it is being measured through self-reporting).

Until we invent some sort of non-obtrusive brain observability system (like a no-op continuous observability implant) that can take precise and accurate measurements with timestamps that can be correlated with other measurements taken across the boday of a person living their normal life, it is going to be difficult to form an effective study for this.
