Is it normal that whenever i sneeze i have an orgasm?

Whenever I sneeze, I have an orgasm! Is this normal?
When i was having sex with my boyfriend last week, right when we were both reaching orgasm, i sneezed really loudly, and for some reason, even though i was on the verge of an orgasm, i did not have one. Two days ago, however, I sneezed (because of my allergy to pollen) and I had a vibrant orgasm, lasting the duration of the sneeze (1-2 seconds.) I tried having sex again, and i did have an orgasm, but i still have an orgasm whenever i sneeze!
