<human>: I recently started training at my new work place within the last month. My
coworker - let's call him Paul - started around the same time. He is full time and I am part time.

I kind of the got the impression he was on the douchier side of the spectrum when we began training together and he referred to women as "females" but I let it go. He's pretty obnoxious but I figured whatever, that's just his personality and as long as he stayed professional I didn't care.

Yesterday he took my training notebook and pretended to read it like it was my diary. Ok whatever, annoying but that's fine. He then proceeded to pretend to read in my voice: "I fingered myself in study hall today." I was pretty shocked and disgusted and let him know and he apologized. 

Then we were doing something else (our job is pretty physical) and he was looking down at his feet and I asked him to look up so that we would both be in a safer position (and he could see where he was going) and he said "Don't worry, I'm not looking at your titties." This time no apology, just laughter.

My place of work has a very small staff. Just him, me, and my two supervisors. I am wondering if I should wait for another incident to report him because honestly, I don't know that he'd be dismissed for his behavior and if they just give him a warning I've effectively created a hostile work environment for myself.

We've also both signed a one year contract and breaking it would cost me upwards of $4k. 

It's worth noting that my workplace is very conservative and traditional, especially in terms of gender roles and men are more desirable for the position we both occupy so favoritism may come into play.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: my coworker has begun sexually harassing me and I'm not sure it's worth reporting or if I should just continue to handle it myself more firmly.
