>It does matter. It makes it worse that they were still in formative years.
You are not wrong about the comparative "worse". But going around flashing people for your gratification is deviant behavior. Flashing over-18 women is wrong. Flashing underaged young women is even more wrong. This is exactly what I mean about "hinky". Your tone is defensive even as you are entirely correct.
I have a challenge for you. Take that entire blog post, rewriting and summarize it in 100 words or less. Then spend the rest of the blog post on what you can actually do for an employer and why your past won't affect a future employer. Sell yourself. The blog post as is crap if the intent is to sell yourself.
