WTF happened!???!

Me & my man we're having sex last night, & he pulled out & pulled me sideways on the bed closer to him & my hands started shaking a little & tingling really bad & they were stuck. Like my muscles.. it took strength to straighten my fingers out.. what happened!??? I was freaking out but laughing & he was like what!?? & we continued to have sex & they were fine after. Three years together & that's never happened
