Snap scam or am I overthinking?

A few weeks ago I added this guy from sniffles on Snapchat. I’m in my mid 20s but I’m new to this. I think this guys is super hot from the pics he’s sent and I believe he is out of my league. We have traded spicy videos and pics (no face), but I was always hesitant about sending face. He is a bit spotty with answering sometimes he opens the message the next morning and doesn’t reply even if it’s a question. I feel like I shouldn’t have but I sent two face pics (1 sec) which he replayed each time. I don’t know if I’m getting scammed or if this is normal. I am dl so if he is a “pic collector” or anything what is the worst he can do? Any advice?
