I fingered a pussy

Or she may have applied lubricant gel that has numbing medication on it, like xylocaine.

Or, you might be a troll.

Trolls have no feelings

If it had been me，your whole body would have been numb。

Also，we trolls have feelings too！！ Stop discriminating.

Feelings despite the lack of a brain?

This seems very unusual. You lost feeling in your finger when you put it inside of her? Was her pussy moist? If it was - then it could have been a numbing agent from a condom.

You weren’t in San Jose were you? I’m not sure if chloroform has an effect on fingers -

Did she have huge tits? If so I may know who you are talking about

Yes, it's normal. Also, now would be a good time to start taking a songwriting class so you can write a few love songs for her. There is a member here, juicebox69, who in exchange for a performance fee may record them for you in his studio.

To clarify - on ppwh’s post - Juicebox69’s recording studio looks a lot like a van parked down by the river....
