[ NSFW ] Ever had an experience where you had a big release out of something seemingly mundane?

Forgive me but I think my painkillers are making me feel fuzzy and high and well, weird.

I just recalled what a female friend told me years ago about a car ride where she sat beside this guy whom she just met and had an orgasm right then and there when all they did was sit, their legs touching. He had no idea what was happening.

She said she shivered with great pleasure. Is this possible with guys? And I wonder if this happens with other women as well?
