<human>: Can you condense the text into a few key points?

I've known this guy for about a year (we met at our casual job), and he's really cool. He can be a little out there sometimes, but he makes me laugh and I think it's adorable how obvious it is sometimes that he wants my attention. Lately, I've kind of had a thing for him, and I'm not sure how he's feeling about me. He added me on snapchat a few weeks ago, and we've been talking since. 

Last night, he snapchatted me, which was nothing out of the ordinary, but he randomly just said "nudes?" in a snap and I replied with "are you asking me for nudes?" and then he replied "maybe". After some time talking about why I would never send nudes (personal reasons) we continued the conversation and then he randomly sent me a partial dick pic...I replied with a subject changer, but then he sent another partial nude. I basically told him to cool it and he said "sorry" but I'm not sure how to feel about this.

I'm not sure if he likes me or just wants to see me naked or what...I get that he's a teenage boy but I really don't know because I don't have tons of experience with guys...
<bot>: Casual coworker friend of mine brought partial nudes into our snapchat conversation. I'm super inexperienced and don't know what to do/what this means. Help!
