One trope I really like in real life is I Didn't Mean to Turn You On: http://tvtropes.org/pmwiki/pmwiki.ph...eanToTurnYouOn
Basically, when one person turns on the other without intending to. Has this sort of thing happened to anyone in real life, on either side?
Once in college, a friend of mine told me how her favorite beach back home was Black's Beach. When I asked her, "Isn't that a nudist beach?" She replied, "Yeah, that's what makes it fun." She didn't get further into it, but damn if that didn't make her the star of my fantasies for months.
Another time, a friend confessed how she once gave a blowjob on a mostly empty airplane. Same result. I fantasized about that a lot. Eventually even turned it into a story.
So how about you guys? Ever unintentionally turned someone else on or been turned on yourself?
