How can humans feel nothing when touching their own bodies with their fingertips but feel wonderful sensations when touched by someone else’s fingertips?

In: Biology

I am guessing here but I guess it’s because of the signals your own touch sends to your brain compared to someone else’s touch.

Your nerves/brain know what is expected when you are creating the action. With another interacting with you, they don’t. Another’s touch also is a socal interaction leading to other brain signals.

You can hug yourself, but the hug from another shows a level of trust. We are socal creatures.

Your body is actually feeling and sensing lots of stuff all the time. To keep you from having a sensory overload, your mind blocks out some of that sensory data because it’s not super important to you at the moment.

There’s usually nothing inherently dangerous or surprising about touching yourself, so your mind just says the sensory information isn’t super important, so you “feel” nothing.

You don’t get this same sensory blockage from someone else touching you because that contact can either be good social contact, or bad dangerous contact. Your mind doesn’t know so it makes sure you are aware of where you are being touched.
