Short informational monologue by Anne Truong MD describing that humans have 30+ erogenous zones (about 12 around the penile area) and explaining genital reflexes: light touch can trigger sensory signals to spinal nerves (S2–S4) producing involuntary erections or reflex sensations (examples: wind, brushing); younger people may have less voluntary control.

You know that you have more than 30 erogenous zone in your body and with 12 of it just in around the penile area. So touching. So it's a reflex. So if you touch and then it sense, then there sends sensation to the nerve in the spinal cord. It goes in a loop like this. Sometimes it can even occur with just the slightest touch, or even just wind blowing near your. That's called reflux. So it goes to the spinal cord, the nerve at S2 and S4. And that causes that reflex. Sometimes kind of happen an embarrassing moment, right? Or sometimes kind of happen, you're brushing against somebody and whoa, there goes your. Sometimes you can't even control it. So the younger you are, you may notice that you can't control it as much.
