Is it possible for a female to orgasm while thinking of nothing sexual ?

I was just about to watch the L word while picking a scab on my forehead (from a curling iron) .. and just as i paused the intro to the show (to get some vaseline or something), my vagina dripped this white substance. It wasn't discharge but it looked like i had squirted myself because this clearish white stuff just dripped from down my leg (& i don't wear underwear in bed so i noticed right away).it even smelled like *** but I wasn't thinking of anything sexual at all.I thought this only happened to guys...........what is this?
