Anyone else??

So I am 22 and have been with my boyfriend for 3.5 years, I have never had an orgasim before. Once we started long distance and we would have sex, right after we’d finish I’d sneeze 3-4 times in a row, this happens often now. I’ve read that this is a way women have orgasims but just curious if it happens to anyone else. Lol. TIA :)
