What Causes Slurring Of Speech And Crying While Reaching Orgasm?

we have just made love, my partner was highly aroused for a very long time, she didn t actually reach orgasm but was on the edge for a very long and very intense time. She was somewhat distressed that her whole head was numb, her face mostly, her feet and hands were tingly. she was crying and asked me just to hold her. Nearly an hour later, her speech is slurred and a little louder as if drunk, she is giggly too as if inebriated. does she need to see a Doctor? Thanks if you can help. I am her female partner.
