Okay guys need your
help.... I want to make sure I did the right thing. I messaged this girl off POF, her profile says she's 18. Very cute. Tons of pics so didn't look fake to me initially. Anyhow, after a few messages back and forth she gets a lil sexual.... which i found pretty forward for someone so young(first red flag) but I keep chatting and she says she might delete her profile because all the guys on pof are so disrespectful and asks that we talk through text. I agree and we start a text convo...
First chat she asks me if I am going to the gym and I should send her a pic of all my sweaty muscles. I thought she was just being flirty so I don't do it just keep teasing her. Next day I text her randomly and she gets sexual through text again saying she want's to know "what I'm packing" I STUPIDLY decide to fall for it and send her a pic of my junk. She tells me it looks great and I should send her more pics. I don't but send her some G-rated ones of myself. She then says we should talk later. I call her that night but she doesn't pick up.
Next day I get a call from her phone and I don't pick up because it's during my lunch. Next thing you know I get a text from her number saying,"son this is Mr. Cunningham and I've reported you to local authorities for sending pics to my 15year old daughter. Shame on you, etc" He doesn't ask for money but I

freak out immediately and could smell the scam or what I thought was a scam so I block the number and am crossing my fingers that this guy will disappear once he realizes I have him blocked and won't respond to anything.
Am I doing the right thing not responding at all? I deleted my POF and screen captured the girls profile that CLEARLY shows she's 18. And her profile is still active, which I find very strange.... Also I looked up the phone number that called me and its a VOIP phone.(619-760-2512)
