It is usually "flirting" if a guy calls you pretty.
However, you should be alert when someone haven't really talked to much wants to connect with you on a really intimate medium right away, like in the case of this guy...you only talked with him for a little bit and then immediately wanted to see you on webcam.
If he was just a friend or liked you for more than just your looks, he would have spent much more time actually chatting with you and getting to know you *as a person* instead of immediately wanting to see your face and body on webcam.
I agree that this is a little exploitative: guys shouldn't be treating you like that. As a girl who was very naive with guys around your age, I can tell you that the attention from showing off your body to many people isn't worth it, and I'm glad you see that. However, guys around your age are generally...erm, horny and mostly just wanting one thing, so that's another thing you should keep in mind.

Given a “tentative” diagnosis as a child as I needed services at school for what was later correctly discovered to be a major anxiety disorder.
This misdiagnosis caused me significant stress, which lessened upon finding out the truth about myself from my current and past long-term therapists - that I am an anxious and highly sensitive person but do not have an autism spectrum disorder.
My diagnoses - social anxiety disorder and obsessive-compulsive disorder.
I’m no longer involved with the ASD world.
