so i was in english class and stayed behind to nap

I ended up not being able to sleep so i just sat there with my head down on my desk

anyways idk what i was thinking about but after about a half hour i started focusing on how my legs felt

as i focused on them they started feeling tingly and the feeling moved up to my abdomen

as i focused more and more it got tinglier and tinglier until it felt identical to an orgasm except it was from my toes to my ribcage, then i got freaked out and just got up to use my phone.

i was fully conscious this whole time

can anyone explain what this was??
