Chewing on someone else's straw

I got a collection of reusable cups from Yerdle. I got them with the idea in mind that I could take them to work and not worry about if they get broken. They all came with straws. Everything was in good shape, except one straw. 

It is a straw someone has meticulously chewed on. 

So much so that the top edge is almost uniformly worn down into a sort of massaging pattern. At first I was disturbed. Why would my lips touch something someone else has chewed on. I boiled the straw and its straw brethren. It went through the dishwasher a few times. 

It went into the cup with the rest of the reusable straws; about 10 or so. Only, it likes to find its way into my hand whenever I need a straw. It looks dirty. It feels weird. But it has become my favorite straw.

Being an "A typer" I had to choose one fixation over another: oral or anal. Thankfully, I am the former. I fidget. I chew on things. I do the leg bouncy thing. This straw lets me chew on it. It doesn't break. It has cracked, but not all the way through. It remains strong. 

It's less strong brethren have cracked or broken under my forced mastication. 

It is currently in my iced tea. It is currently entertaining my mouth as I am working. 

It is, in fact, not chewed on at all. It seems someone, in its former life, forced it into some sort of cap or enclosed space meant for a much smaller straw. 

Yeah, we'll go with that.
