Tactile enhancement is an overall increase in both the intensity of a person's sense of touch and their awareness of the physical sensations across their body. At its highest level, this becomes extreme enough that the exact location and current sensation of every single nerve ending across one's skin can be felt all at once. In contrast, most people can only maintain awareness of the tactile sensations that are relevant to their current situation in their sober state.
This effect can result in tactile sensations such as touching, hugging, kissing, and sex becoming greatly enhanced in terms of the pleasure they induce. However, it can also result in an over-sensitivity of the skin, which causes the same sensations to become uncomfortable and overwhelming.
Tactile enhancement is often accompanied by other coinciding effects, such as spontaneous bodily sensations and physical euphoria. It is most commonly induced under the influence of moderate dosages of psychedelic compounds, such as LSD, psilocybin, and mescaline. However, it can also occur under the influence of stimulants, cannabinoids, and certain dissociatives, such as 3-MeO-PCP.
