Open Question: is it normal to have an orgasm just from being tickled?

[feedcrawler]

Or am I strange?My new boyfriend has a fetish for feet. A few weeks ago I indulged him for the first time and allowed him to tie me to my bed. He proceeded to tickle the bottoms of my feet for a long time.I'm a very ticklish person and I laughed and screamed. I couldn't even curl my toes as he'd somehow tied those too.All of a sudden and without warning I had an orgasm, but I wasn't aware I was aroused. His scratching my soles went from hideous torture to making it one of the most intense orgasms I have had.Is it normal to experience orgasm just from having your feet tickled? Or to experience spontaneous orgasm without first feeling aroused? My BF hadn't seen it happen before (though he thought it was the coolest thing ever!) and I'm quite nervous about putting myself through it again.
