Ok, this is something I'd never experienced before until this past weekend. Sunday morning my bf and I had a very heated session. I orgasmed several times and afterwards I noticed that my fingers had a tingling sensation (kind of like when your foot is asleep). It was in every single finger and it lasted for quite a while afterwards! Has anybody ever had this? I just chalked it up to bloodflow of something.
I once went out with a guy with electric fingers that could raise hairs without even touching. It was totally bizzare.
Were you supporting yourself on your hands for any length of time? If so, you could have caused them to "fall asleep" due to a restricted blood flow. Peace.
Tingling fingers is never a good sign, as someone said, it's the sign of blocked bloodflow.. and that's never good.. whatever it is you was doing, be careful.
