I challenge someone to scientifically test out this theory, that all male/female interactions have an undertone of sexuality.
The next time you interact with someone and you think they're flirting or whatever, ask them if they would like to give you oral pleasure?
Then report their responses in this thread.
Obviously this would take balls of steel, so I doubt anyone will take up this challenge.
I've always wondered this though, what would a woman say if I bluntly asked her to give me oral pleasure?
