I’ve never cum from something more unexpected than a wet dream. Wondering what your most unexpected orgasm was and how it made you feel. Did it become a go-to or did you actively avoid triggering one again?
For example, cumming during a core workout, cycling, riding a rollercoaster. Any other even more unusual examples?

I can’t imagine anything as a guy apart from wet dreams. I’ve heard this about prostate exams but I can’t imagine that really happening.
