LOL
The second woman that I dated (~7 years off and on) could do this. When she'd get stressed, she'd have an orgasm. While in undergrad, she'd sometimes get anxious enough during exams that she'd orgasm while taking the test. We lived in the Midwest, and her truck slid off the Interstate once after coming to visit me; her truck is spinning around on the ice, and she's having an orgasm.
She told me that these types of orgasms were the best she'd ever have. She was a real pain in the ass, but otherwise unremarkable (even in bed).
Is this now an L&R thread?
