<human>: I trade Snapchat with a whole bunch of my family members, including a younger make cousin. He just sent me a Snapchat of his dick. I am hoping he sent it to me on accident or something? But I still feel really violated. 

I should probably tell his parents right? I text sometimes with my uncle, but I  guessing this requires a phone call? Ugh. I know that is probably what I should do, but I feel super weird and gross about the whole thing, and I could use some general advice. 

And just some additional info: I already blocked him on Snapchat. I do not have a close relationship with the cousin himself, and I don't really want to talk with him about this.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: I need some advice on how to handle the situation. My little cousin sent me a Snapchat of his dick - I should talk with his parents, right?
