50V is pretty much the limit that is still considered safe for humans to get in direct contact with.
And by safe it means 'won't die' not 'pleasant feeling' still be careful with 50v!
With dry hands it shouldn't be bad, with wet or sweaty fingers it probably can become quite a "shocking" experience.
If there is some liquid poured over the connector or if the cable is damaged, this could really become nasty.
As a teenager I touched a phone plug with my tongue. While it only delivered 48V it was far from being pleasant
Touching a 9V battery to your tongue isn't pleasant.
Licking a Nintendo game card is also not pleasant.
Which Nintendo console, what game and for what purpose?
Having done both I can assure you that the phone plug experience is far sharper. It's the similar "lemony" shock, but far far stronger
You're just lucky it didn't ring at the time!
At uni we learned that 30V can penetrate skin in the right (wrong?) conditions. Once it's through the skin, your body conducts really well, so even a tiny amount of current can stop your heart. But you need a path for the current to get across your heart, so I'm guessing that even if 30V gets under your skin, you'd have to be pretty unlucky for it to form a circuit through your heart.
plenty of grounded things you might be gripping with your other hand at the same time :(
Mmm yes 50 V over pins that are half a millimetre apart. I see no problem with this. No problem at all.
