She's an adult woman; if that "cutesy" thing in particular is what gets you off then yeah you are a pedo.. but.. she's still a fucking adult lol.
You guys and your "if you are attracted to 18-20 year olds are pedos" shtick just comes across bitter and incely.
Your first sentence shows that you understand the issue, your second shows that you don't.
I'm sure there are 19 year old women out there that are very mature, and that across a crowded bar could easily pass for 25. She ain't one of them, she's a young woman trying to look and act like an even younger woman. Yeuch.
Also, 'bitter and incely' is one of those reee-style catchphrases that suggests you're talking to preconceived stereotypes in your head, not actual human individuals.
