I used to believe the word "blowjob" encompassed both male and female oral sex. I couldn't see why not, it's a stupid word anyway. And it never particularly occured to me to ask about it.
However, once in school some madness took over me. After watching "American Pie" and a certain scene in that movie... I sat in front of two girls throughout one of my classes and decided on that day, out of some spurt of insanity, to offer one of them a blowjob.
Neither of them were particularly impressed.
