There are a lot of sites out there that say that staring at the color blue during sex increases the intensity of orgasm. Some go so far as to attribute this to the “angle at which the optic nerve enters the brain.” Nonsense. The angle at which a nerve connects to the brain does absolutely nothing to the nerve impulse. Even if it did, there is zero connection between the brain’s interpretation of color and the brain’s interpretation of touch sensation. Besides, I’ve tried staring at the color blue, and it didn’t work.
Staring at a blue surface does absolutely nothing for your orgasm.
