Or, in this case, with a Fucksaw. Yes, you read that correctly. I said fucksaw.
Imagine you're in class. It's Human Sexuality, so you're bound to get some graphic details here and there, right?
Now imagine there's a naked woman in front of the class on whom a sex toy is being demonstrated. Awkward!
I mean, even if that kind of thing floats your boat, how weird would the whole situation be? Maybe if it was just you and the naked woman, sure. Or even you, the naked woman and a third party (sharing is caring?). But it's you, the naked woman, the demonstrator, a class full of other students, the professor, maybe a TA or two... Yeah, any chance of that being anything less than exceedingly awkward went right out the window.
If nothing else, you'll never look at a saw the same again.
