My boyfriend and I just recently started having oral sex, and last night was the first time I'd ever orgasmed from it. It was crazy intense, he was also fingering me and hitting my G-Spot, but most of the intensity was in my clit. It was the most intense orgasm I've ever had and like two seconds later I started sobbing unconrollably. He kept asking me what was wrong, but I couldn't really talk. He thought he had upset me or hurt me somehow! The crying lasted for probably less than a minute, and turned in to laughter that I couldn't control, but at least I was able to explain that sometimes when orgasms are really intense, people cry. Or laugh. Or both, in my case, haha. I was afraid I'd totally killed the mood, but I went down on him a little while later after my giggles had subsided, and he came very quickly.
So thank you, VaginaPagina, for teaching me about orgasms!
