They do hurt, I am weird in a way I used to do a lot of electrical and got shocked on a daily basis, So me and my friends had all been drinking on night and someone had a taser. Yes I tasered myself ad realized that it didn't bother me it felt like 2 bee stings but no real pain for me, Fast forward a couple of years I was working at a gun store and we sold them things like crazy and the most common question was will it permanetly damage the suspect, Well anytime that question was asked the owner would start laughing and I would take the taser stick it to my thigh and key it up. It became kind of a joke after on husband thought well if he can do that I can too,, LOL Big mistake I had to help him up of the floor LOL
